Question

A rectangular pyramid has a height of 9.5 centimeters and a volume of 494 cubic centimeters. What is the area of the base of the pyramid? *

Answer 1

Answer:

Formula for taking out volume :

1/3(area of base)× height

Let the area of base be 'x'

height = 9.5 cm

volume = 494 cu.cm

According to the question:

1/3(x)9.5=494

9.5x/3=494

x=494×3/9.5 = 164.666667(approx)

Therefore the required base area is 164.67 cm (approx)

Answer 2

Area of base= 3V/h
h= 9.5
Volume= 494 cu cm
Answer:
=3* 494/9.5
Area of base= 156 cm^2
