Question

he length, breadth and height of a cuboid are 16cm, 14cm and 10cm respectively. Find the total surface area of the cuboid.

Answer 1

Answer:

l = 16 cm

b = 14 cm

h = 10 cm

TSA of cuboid = 2 (lb + bh + hl)

$= 2(16 \times 14 + 14 \times 10 + 10 \times 16) \\ \\ = 2(224 + 140 + 160) \\ \\ = 2 \: (524) \\ \\ = 1048 \: {cm}^{2}$

Hope it helps.

Answer 2

Answer:

l = 16 cm

b = 14 cm

h = 10 cm

T.S.A. of cuboid = 2 h (l+b)

                          = 2 x 10 (16+14)

                          = 20 x 20

                          = 400 cm²
