a suitcase with measure 80cm x 48cm x 24cm is to be covered with a tarpaulin cloth. How many metres of tarpaulin of width 96cm is required to cover 100 such suitcases?
Hi!
Here is the answer to your question.
Dimensions of the suitcase are 80 cm × 48 cm × 24 cm
Total surface area of a suitcase
= 2 (lb + bh + lh)
= 2 (80 × 48 + 48 × 24 + 24 × 80)
= 2 (3840 + 1152 + 1920)
= 13824
Width of the tarpaulin = 96 cm
Length of tarpaulin to cover 100 such suitcase = 144 × 100 cm = 14400 cm = 144 m
Cheers!
