Question

QuestionA cube is 3.2 meters on each side. Find its a. volume and b. surface area. Do not round the answer.

Answer 1

We will solve as follows:

*The volume is given by the following expression:

$V=a^3$

So:

$V=(3.2)^3\Rightarrow V=32.768$

The volume is equal to 32.768 cm^3.

*The surface area of a cube is given by the expression:

$A=6a^2$

So:

$A=6(3.2)^2\Rightarrow A=61.44$

The surface area is equal to 61.44 cm^2.
