At a space station, Nova, Luna, and Emek received a solar storm warning. They needed to cover a rectangular supply crate that was 6 meters long, 4 meters wide, and 3 meters high. Nova found the areas of the three different face sizes: 24, 18, and 12 square meters. Luna noted that each face had an identical opposite face. Emek doubled the three areas and added them: 48 + 36 + 24 = 108 square meters. They prepared 108 square meters of protective material, covered every face, and secured the crate before the storm arrived.

Hint
Find the area of a rectangle by multiplying its length by its width.
The crate is 6 meters long and 4 meters wide. What is the area of one 6-meter by 4-meter face?
10 square meters20 square meters24 square meters48 square metersCorrect! A 6-meter by 4-meter face has an area of 24 square meters.
Try again. Multiply the two side lengths of the rectangular face.
Next🎉 Congrats! You got this question!
Hint
First find the area of one 6-meter by 3-meter face, then account for its identical opposite face.
The crate has two faces that are each 6 meters by 3 meters. What is the total area, in square meters, of these two faces?
Correct! The two 6-meter by 3-meter faces have a total area of 36 square meters.
Try again. Find the area of one face, then double it because there are two matching faces.

Hint
There are two of each of the three different face sizes.
Which expression correctly finds the total surface area of the 6-meter by 4-meter by 3-meter crate?
24 + 18 + 122 * (24 + 18 + 12)6 * 4 * 32 * (6 + 4 + 3)Correct! Add the areas of the three different faces and double the sum to include their opposite faces.
Try again. Remember that every face has an identical opposite face.
