determine (a) the volume and (b) the surface area of the three-dimensional figure. when appropriate, use the pi key on your calculator.

Step-by-step explanation:
The figure above is a cube since all it's sides are equal
Volume of a cube = l³
where l is the length of one side
From the question
l = 5
So the volume of the cube is
Volume = 5³
Surface area of a cube = l²
= 5²
Hope this helps you
