Answer:
1.5 in³
Step-by-step explanation:
Several formulas come into play:
P = 4s . . . . . . . perimeter of square of side length s
A = s² . . . . . . . area of square with side length s
V = 1/3Bh . . . . volume of a pyramid with base area B and height h
__
Using the given numbers, we find ...
(5.1 in) = 4s
s = (5.1 in)/4
A = ((5.1 in)/4)² = 1.625625 in²
V = 1/3(1.625625 in²)(2.7 in) = 1.4630625 in³
The volume of the pyramid is about 1.5 cubic inches.
