In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
pyramid side:
h = 3.25 ft
b = 2.5 ft
square base:
s = 2.5 ft
gallon of gold paint:
400 ft²
Step 02:
surface area:
square base area:
A = s² = (2.5 ft)² = 6.25 ft²
total pyramid sides area:
A = (b * h) / 2
A = (2.5 ft * 3.25 ft) / 2 = 4.0625 ft²
total pyramid sides area = 4 * 4.0625 ft² = 16.25 ft²
total trophy area:
total trophy area = 6.25 ft² + 16.25 ft² = 22.5 ft²
maximum number of trophies:
maximum number of trophies = 400 ft² / 22.5 ft² = 17.78
The answer is:
square base area = 6.25 ft²
pyramid side area = 4.0625 ft²
total pyramid sides area = 16.25 ft²
total trophy area = 22.5 ft²
maximum number of trophies = 17
