Question

how many square centimeters of wrapping paper will be used to wrap the shoe box measure 28 and 14 and 10 cm?

Answer 1

Answer:

Surface area of shoe box which is cuboid = Surface area of wrapping paper

2(lb+bh+lh) = 2[(28*14)+(14*10)*(28*10)] = 2[392+140+280]

2*812 = 1624 cm square

Hence, 1624 cm^2 wrapping paper will be required for wrapping the shoe box

Answer 2

Answer:

1624cm²

Step-by-step explanation:

Total surface area of cuboid is 2lb+2bh+2lh

Tsa= 2*28*14 + 2*14*10 + 2*28*10

Tsa= 784+280+560

Tsa= 1624cm²

Hence we need 1624cm² wrapping paper to wrap the shoe box.
