Answer:

400 cm² of stickers

Step-by-step explanation:

A wooden box has the shape of a rectangular prism.

To solve for the above question, we would be using the formula for the Surface Area of a rectangular prism to calculate how much stickers are required .

The formula for the surface area of a rectangular prism =

A=2(wl + hl + hw)

l = Length = 20cm

w = Width = 4cm

h = Height = 5m

Hence,

= 2 × (4 × 20 + 5 × 20 + 5 × 4)

=400 cm²

Therefore, 400cm² of stickers would be needed to cover the wooden box.
