Volume and Total Surface Area of Solids

For the volume of solids : ​

V = Ah

where : - A = area of the cross section of the solid

h = the height, length or thickness of the solid​

Egs. Calculate the surface area of the following wedge.

(rectangular based pyramid)

​T.S.A. = 4131 + 252 = 4383cm²

AVERAGE SPEED

​

Egs.

1. If a plane covers 1200m in 3 seconds, what was the speed of the plane?

s = d/t

= 1200/3

= 400m per sec or m/s
