The measurements of a luggage box are 48×36×28.How many sq.Cm of cloth is required to make a cover for the box

Answer 1

length of box=48cm

breadth=36cm

height=28cm

total surface area of box =2(lb+bh+hl)

2(48*36+36*28+28*48)

2(1728+1008+1344)

2*4070

8140

hence cloth required to cover the box =8140 cm^2
