Question

Jack made a bird house which has a cuboidial top with dimensions 8 m $\times$ 2 m $\times$ 3 m. In the bottom, he made a entry passage with dimensions 4 m $\times$ 2 m $\times$ 5 m. Calculate the total volume of the bird house.

• A. 88 cubic meter
• B. 98 cubic meters
• C. 78 cubic meters
• D. 108 cubic meters

Answer 1

The correct option is A 88 cubic meter

The volume of the bird house can be calculated by combining the volume of both the portions.

Volume of cuboid
= Length $\times$ Width $\times$ Height

Volume of upper cuboid = 8 $\times$ 2 $\times$ 3
= 48 cubic meters

Volume of lower cuboid = 4 $\times$ 2 $\times$ 5
= 40 cubic meters

Total volume = 48 + 40
= 88 cubic meters
