The top of a gate post is in the shape of a square pyramid. the height of the pyramid is 5 inches and each side of the base is 7.4 inches. find the volume of wood needed to make the top of the gate post. round to the nearest tenth.

91.3 in³

Step-by-step explanation:

The formula for the volume of a pyramid is:

V = where B=area of the base and h=height of the pyramid

Given the dimensions in the problem and that the pyramid has a square base, we can first calculate the area of the base:

A = 7.4 x 7.4 = 54.76 in²

Multiply the area of the base x height of the pyramid:  (54.76 x 5) = 273.8

Divide by 3 (multiply by ): 273.8/3 ≈ 91.3 in³

ian gonna lie that is way to much

what is the answer?
