The dimensions of a cuboid are 7 cm, 11 cm and 13 cm. The total surface area is :
A. 311 $${\text{ c}}{{\text{m}}^2}$$
B. 622 $${\text{ c}}{{\text{m}}^2}$$
C. 1001 $${\text{ c}}{{\text{m}}^2}$$
D. 2002 $${\text{ c}}{{\text{m}}^2}$$
Answer: Option B
Solution (By Examveda Team)
Surface area :$$\eqalign{ & = {2\left( {7 \times 11 + 11 \times 13 + 7 \times 13} \right)} \cr & = {2 \times 311} \cr & = 622{\text{ c}}{{\text{m}}^2} \cr} $$
