Question

Each side of the cube at the Discovery Science Center in Santa Ana is 64 feet long.

(a)
Find the volume (in cubic feet).
cu. ft
(b)
Find the surface area (in square feet).

Answer 1

V = 262’144 ft^3, surface area = 24’576 ft^2

Explanation:

The volume con be find with this formula =

V = side^3

V = 64^3 = 262’144 ft^3

For find the surface area we can proceed in this way: first of all we can find the area of a face.

A = side^2 = 4096 ft^2

a cube has 6 faces, so we have to the mutiply the value six times.

Surface area = 4096 x 6 = 24’576 ft^2
