Question

Find the volume, total surface area and lateral surface area of cuboid whose dimensions are given.

Length $=15cm,$ breadth $=10cm$ and height $=12cm$.

Answer 1

Volume of a cuboid$=l\times b\times h=15\times 10\times 12=1,800‬{cm}^3$

Total surface area of cuboid$=2(lb+bh+lh)=2(15\times 10+10\times 12+15\times 12)=2\times 450=900$sq.cm

Lateral Surface area of cuboid$=2(bh+lh)=2(10\times 12+15\times 12)=2\times 300=600$sq.cm
