Question

curved surface area of cube and cuboid and total surface area of cube and cuboid

Answer 1

C.S.A of Cube =4a^2
T.S.A of cube=6a^2

C.S.A of cuboid=2h(l+b)
T.S.A of cuboid=2(lb+bh+lh)

Answer 2

Curved surface area of cube = $\large\sf{{4a}^{2}}$

Curved surface area of cuboid = $\large\sf{2(l+b)×h}$

━━━━━━━━━━━━━━━

Total surface area of cube = $\large\sf{2h(l+b)}$

Total surface area of Cuboid = $\large\sf{2(lb+bh+hl)}$
