Answer
$A=6\times 2.5^2=37.5$ square in.
$V=2.5^3=15.625$ cubic in.
Work Step by Step
This solid is a cube as all of its sides are equal.
The volume of a cube can be calculated as:
$V=a^3$
Here:
$V=2.5^3=15.625$ cubic in.
The surface of a cube can be calulated as:
$A=6\times a^2$
Here:
$A=6\times 2.5^2=37.5$ square in.
