The amount of cloth required is equal to the total surface area of suitcasesuitcase is a cuboid
The amount of cloth required is equal to the total surface area of suitcasesuitcase is a cuboidTotal surface area=2(lb+bh+hl)
l=80cm
l=80cmb=48cm
l=80cmb=48cmh=24cm
l=80cmb=48cmh=24cmTotal surface area= 2×(80+48+48×24+24×80)
=2(3840+1152+1920)
=13824 cm2
=13824 cm2Area of 100 suitcases = 100×13824
=1382400
=1382400Area of tarpaulin= l×b
l=?
l=?b=96 cm
Area = l96×l
=96l
=96larea of tarpaulin =area of 100 suitcases
=96larea of tarpaulin =area of 100 suitcases96 l=1382400
=96larea of tarpaulin =area of 100 suitcases96 l=1382400 l = 1382400÷96
=14400 cm
