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
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.
