To calculate the total surface area of the gift box, we need to find the area of each of the six faces and then add them all together.
Face 1: Area = a x b = 66m x 99m = 6534m^2
Face 2: Area = a x c = 66m x 77m = 5070m^2
Face 3: Area = b x c = 99m x 77m = 7623m^2
Face 4: Area = a x b = 66m x 99m = 6534m^2
Face 5: Area = a x c = 66m x 77m = 5070m^2
Face 6: Area = b x c = 99m x 77m = 7623m^2
Total Surface Area = 6534m^2 + 5070m^2 + 7623m^2 + 6534m^2 + 5070m^2 + 7623m^2
= 38454m^2
Therefore, the total surface area of the gift box is 38454 square meters.
Eva wraps a gift box in the shape of a right rectangular prism. The figure below shows a net for the gift box.On the tactile printout of the following graphs, a is 66 meters, b is 99 meters, and c is 77 meters.
