A box needs to be decorated to use as a prop in a play. The bottom and the back of the box do not need to be decorated. What is the surface area of the box that needs to be decorated?

The surface area of a box is given by the formula:

Surface area = 2lw + 2lh + 2wh

Since the bottom does not need to be decorated, we only need to calculate the surface area of the sides and the front.

Assuming that the length (l), height (h), and width (w) of the box are all different, the surface area that needs to be decorated is:

Surface area = 2lw + 2lh + wh = l(w + 2h) + wh = lw + 2lh + wh

Hence, the surface area of the box that needs to be decorated is lw + 2lh + wh.

27+20+20

27 + 20 + 20 = 67

multiply it

27 * 20 * 20 = 10,800

what would a box dimention be if this was the surface area 1880?

To find the dimensions of a box with a given surface area, we need to solve the surface area formula in terms of the dimensions.

Given that the surface area is 1880, we have:

1880 = 2lw + 2lh + 2wh

To solve for the dimensions, we need to consider that there are infinite possible combinations of length (l), height (h), and width (w) that can result in a surface area of 1880.

Here is one potential set of dimensions that satisfy the equation:

Assume l = 20, h = 20, and w = 23:

surface area = 2lw + 2lh + 2wh
= (2 * 20 * 23) + (2 * 20 * 20) + (2 * 23 * 20)
= 920 + 800 + 920
= 2640

Since 2640 is not equal to 1880, this set of dimensions does not result in the desired surface area.

We need to find another combination that satisfies the equation, or it is possible that there is a mistake in the given surface area value.
