Question

A suitcase with measures 80 cm x 48 cm x 24 cm is to be covered with a tarpaulin cloth.
How many metres of tarpaulin of width 96 cm is required to cover 100 such suitcases.

Answer 1

Answer:

144 m

Step-by-step explanation:

Suitcase measures,

length=80 cm

breadth=48 cm

height=24 cm

Area of 1 suitcase= 2(lb+bh+hl)

                             = 2(80 x 48+ 48 x 24+ 24 x 80)

                             =2(3840+1152+1920)

                             =2 x 6912 = 13,824 $cm^{2}$

Area of 100 suitcases=13,824 x 100

                                   = 1,382,400$cm^{2}$

Width of tarpaulin cloth= 96 cm

Length of cloth= $\frac{Area}{Breadth}$

                        =$\frac{1382400}{96}$

                        = 144 m
