Question

A suitcase with measure 80 into 48 into 24 cm is to be covered with a tarpaulin cloth .how many meters of tarpaulin of width 96cm is required to cover 100 such suitcases

Answer 1

The suitcase

l = 80 cm

b = 48 cm

h = 24 cm

therefore,

Total Surface Area = 2(lb + bh + lh)

= 2 [(80*48) + (48*24) + (80 * 24)]

= 2 (3840 + 1152 + 1920)

= 2 * 6912

= 13824 cm^2

Length of cloth required = (area of suitcase/ breadth) * 100

= (13824/ 96) * 100

= 144 * 100

= 14400 cm

= 14400 /100 m

= 144 m
