Question

If I wanted to wrap a present and the box measured 10 cm wide, 4 cm high, and 7 cm long how much wrapping paper would I need to wrap the present

Answer 1

To calculate the amount of wrapping paper needed to wrap the present, you would need to calculate the surface area of the box.

The surface area of a rectangular box can be calculated using the formula:

Surface area = 2lw + 2lh + 2wh

Where:
l = length of the box
w = width of the box
h = height of the box

Plugging in the values:
l = 7 cm
w = 10 cm
h = 4 cm

Surface area = 2(7)(10) + 2(7)(4) + 2(10)(4)
Surface area = 140 + 56 + 80
Surface area = 276 cm²

Therefore, you would need 276 cm² of wrapping paper to cover the present.
