Volume of a combination of solids

Mathematics Class X Surface Areas and Volumes Volume of a combination of solids

Find the volume of the given solid.

Solution

The given solid is made up of two solids i.e. Pyramid and cuboid.

Total volume of the solid = Volume of pyramid + Volume of cuboid

Volume of pyramid $=\dfrac{1}{3}$ Area of base $\times$ height

Given, height = 6 in. and length of side = 4 in.

Volume of cuboid = lbh

Given, l = 4 in., b = 4 in, h = 5 in.

Total volume of the solid $=\dfrac{1}{3}$ Area of base x height + lbh

$=\dfrac{1}{3}\times4\times4\times6+ (4)\ (4)\ (5)$

$= 32 + 80$

$= 112\ \text{in}^3$
