Question

3. A rectangular metal sheet is 8.5m long and 8.8m wide. How many closed boxes of
dimensions 17cm x 19cm x 5cm can be made out of it​

Answer 1

Answer:

Area of metal sheet = 8.5m x 8.8m

74.8 m^2

Surface area of one box = 2(lb x bh x hl)

= 2((17 x 19)+(19 x 5)+(5 x 17)) = 1,006 cm^2

74.8 m^2 = 748000 cm ^2

748000÷1006 = 744 cubes
