Question

The vault shown is in the shape of a cube of each side is 2y^2 feet, find its volumeThe volume of the Wally is: Simplify

Answer 1

We have

Side of the cube is 2y^2 feet.

Then, The volume of a cube is given by

$V=s^3$

Where s = side = 2y^2

So:

$V=(2y^2)^3$

Apply the exponent law

$\begin{gathered} V=2^3\cdot(y^2)^3 \\ V=8(y^2)^3 \end{gathered}$

Apply the property of exponents

$V=8(y^{2\cdot3})$

Multiply

$V=8(y^6)$

Answer: The volume is

$8y^6$
