Question

For a cube of side 'a' and a cuboid of length 'l', breadth 'b' and height 'h', match the following.

• A. $2h(b+l)$
• B. $4a^2$
• C. $6a^2$
• D. $2(lb+bh+lh)$

Answer 1

The formulae for TSA and LSA of the cube and cuboid are as given below.

TSA of cuboid $=2(lb+bh+lh)$,
LSA of cuboid $=2(bh+lh)$, where l,b and h are length,breadth and height of the cuboid respectively.

TSA of cube $=6a^2$,
LSA of cube = $4a^2$, where 'a' is the side of the cube.
