Examples of cuboid in the following topics:

  • Volumes

    • The volume of the cuboid with side lengths 4, 5, and 6 may be obtained in either of two ways.
    • of the constant function $1$ calculated on the cuboid itself.
    • of the function $z = f(x, y) = 5$ calculated in the region $D$ in the $xy$-plane, which is the base of the cuboid.
    • For example, if a rectangular base of such a cuboid is given via the $xy$ inequalities $3 \leq x \leq 7$, $4 \leq y \leq 10$, our above double integral now reads:

  • Optimization in Several Variables

    • A packaging company needs cardboard boxes in rectangular cuboid shape with a given volume of 1000 cubic centimeters and would like to minimize the material cost for the boxes.
    • First of all, the material cost would be proportional to the surface area $S$ of the cuboid .
    • Mathematical optimization can be used to solve problems that involve finding the right size of a volume such as a cuboid.

  • Types of Epithelial Tissue

    • The four major classes of simple epithelium are: 1) simple squamous; 2) simple cuboidal; 3) simple columnar; and 4) pseudostratified.
    • Simple cuboidal epithelium consists of a single layer cells that are as tall as they are wide.
    • The important functions of the simple cuboidal epithelium are secretion and absorption.
    • Stratified epithelia can be columnar, cuboidal, or squamous type.
    • Cuboidal epithelium has cells whose height and width are approximately the same.

  • Tarsals, Metatarsals, and Phalanges (The Foot)

    • It articulates with the talus superiorly and anteriorly with the cuboid of the distal group.
    • There are four distal tarsals: the lateral cuboid and the three cuneiforms, located medially.
    • The proximal base articulates with the cuboid bones, and distally with the proximal phalanges, and each metatarsal also articulates laterally with adjacent metatarsals.

  • Epithelial Tissues

    • Cuboidal epithelial cells are cube-shaped with a single, central nucleus .
    • Simple cuboidal epithelial cells line tubules in the mammalian kidney where they are involved in filtering the blood.

  • Thyroid Gland

    • The thyroid gland is made up of many spherical thyroid follicles which are lined with a simple cuboidal epithelium.

  • Arches of the Feet

    • It is composed of the calcaneus, the cuboid, and the fourth and fifth metatarsals.
    • While these medial and lateral arches may be readily demonstrated as the component antero-posterior arches of the foot, the fundamental longitudinal arch is contributed to by both, and consists of the calcaneus, cuboid, third cuneiform, and third metatarsal: all the other bones of the foot may be removed without destroying this arch.

  • Magnetosomes

    • Three general crystal morphologies have been reported in magnetotactic bacteria on the basis: roughly cuboidal, elongated prismatic (roughly rectangular), and tooth-, bullet-, or arrowhead-shaped.

  • Semen

    • The ductuli efferentes possess cuboidal cells with microvilli and lysosomal granules that modify the semen by reabsorbing some fluid.

  • Muscles that Cause Movement at the Foot

    • Attachments - Originates from the plantar surfaces of the cuboid and lateral cuneiform bones in the sole of the foot and attaches to the big toe.
