Leonard is going to construct a pyramid with cardboard for math class. Find how many square inches (in.2) of cardboard he will need. Use 4(1/2)bh+b2 , where b , the base of the pyramid, is 3 in. and h , the height of the pyramid, is 8 in.(1 point)
in.2
Plugging in the values for b = 3 and h = 8 into the formula, we get:
4(1/2)(3)(8) + (3)^2
= 4(4) + 9
= 16 + 9
= 25
Therefore, Leonard will need 25 in.2 of cardboard.
