Question

Find the surface area of the cuboid of length, breadth and height is 3.6 cm, 1.5 cm, 5 cm​

Answer 1

l = 3.6 cm

b = 1.5 cm

h = 5 cm

Surface area = 2( lb + lh + bh)

= 2[ (3.6×1.5) + (3.6 × 5) + (5× 1.5)]

= 61.8

Answer 2

Answer:

61.8

Step-by-step explanation:

surface area of cuboid =2(lb×bh×lh). 2(3.6×1.5 + 1.5×5 + 3.6×5) 2(5.4 + 7.5 + 18). =2(30.9). =61.8
