Answer:
3042in³
Explanation:
Volume of the square prism = Base area * Height
Since the base is a square;
Base area = s²
s is the side length of the square
Given s= 13 inches,
Base area = 13²
Base area = 169in²
If he wants the height 6 inches longer than the width and the length, then the height will be:
Height = 13 + 6 = 18 inches
Get the volume
Volume of the square prism = 169in² * 18in
Volume of the square prism = 3042in³
