The volume of the solid created by joining two right rectangular prisms is 360 cubic cm

Volume of prism

The formula for calculating the volume of prism is expressed as:

V = lwh

where

l is the length

w is the width

h is the height

The volume of the given solid is expressed as:

V = (4cm * 4.5cm * 5cm) + (5cm * 4.5cm * 12cm)

V = 90 + 270

V = 360 cubic cm

Hence the volume of the solid created by joining two right rectangular prisms is 360 cubic cm
