Question

the great pyramid of Cheops is a square based pyramid. the base has sides of 230m and the height is 147m. using the same material. what would the height be if you gave the base sides of 220m?

Answer 1

Explanation:

A ratio problem

230 sides is to 147 height as 220 sides is to an unknown height X

230/147 = 220 / X solve for x ( since 220 < 230 X should be < 147)

X = (220)(147) / 230

X = height = 140.6 m is less than 147
