The surface area of a box can be calculated by finding the area of each of its six sides and then adding them up.
The box has three pairs of sides - the top and bottom, the front and back, and the two sides.
The top and bottom of the box both have an area of 8 inches by 10 inches, so the total area for these two sides is 2*(8*10) = 160 square inches.
The front and back of the box both have an area of 8 inches by 3 inches, so the total area for these two sides is 2*(8*3) = 48 square inches.
The two sides of the box both have an area of 3 inches by 10 inches, so the total area for these two sides is 2*(3*10) = 60 square inches.
Adding up the areas of all six sides gives a total surface area of 160 + 48 + 60 = 268 square inches.
Therefore, the surface area of the box is 268 square inches.
what is the surface area of a box that is 8 in 3 in 10 in?
