Question

a suitcase with measures 80 cm × 48 cm × 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

Since all the sides of the suitcase has to be covered with tarpaulin, We need to find TSA of the box.
Total Surface Area = 2(LB + BH + LH)
L=80 cm
B=48 cm
H=24 cm
TSA = 2(80*48+48*24+80*24)
=>TSA = 2 * (6912)
=>13824 cm²
For 100 suitcases area of tarpaulin needed =>
100 * TSA
=> 100 * 13824
=> 1382400 cm²
CentiMetres of tarpaulin cloth required =>
1382400/96
=>14400 cm=>144 m
