# Find the surface area of a cuboid 10 m long, 5 In broad and 3 m high.

 A) 105 sq m B) 104 sq m C) 170 sq m D) 190 sq m

 D) 190 sq m

Given that, l = 10 m, b = 5m, h = 3m

lb =$$\Large 10 \times 5$$ = 50, bh = $$\Large 5 \times 3$$ = 15, lh = 10 x 3 = 30

Therefore, Surface area of a cuboid

= $$\Large 2 \left(lb+bh+lh\right)$$

= $$\Large 2 \left(50+15+30\right)$$

= $$\Large 2 \times 95 = 190 sq m.$$
