Find the volume of the pyramid.

Volume of a pyramid = (B * h) / 3
B = 4 * 4 = 16 meters squared
h = 7 m
Volume = 16 meters squared * 7 meters = 112 meters
112 / 3 = 37.33

Find the surface area of the pyramid.
Surface area of a pyramid = B + (P *s)/2
B = 4 * 4 = 16 meters squared
P = 4 + 4 + 4 + 4 = 16 m
s = 9 m
Surface area = 16 + (16 * 9)/2 = 16 + 72 = 88 meters squared

= 3.14 * 32 * 5
= 141.3 meters cubed
Formula for the volume of a cone
Volume of a cone =
Find the volume of a cone with a radius of 2 m and a height of 5 m.
Volume of a cone = (πr 2h)/3
= (3.14 * 22 * 5)/3
= (3.14 * 4 * 5)/3
= 62.8/3
= 20.93 meters cubed
Formula for the surface area of a sphere
Surface area of a sphere = 4 * π * r 2
Formula for the volume of a sphere
Volume of a sphere = (4/3) * π * r 3
