Question

a wooden box is 1 foot high, 3 feet wide, and 5 feet long. bob is going to use it for a table top and plans to paint the 4 sides and top. how many square feet will be painted? a 15 b 30 c 31 d 46

Explanation:

Step1: Calculate the area of the top

The area of the top is length × width, so \(5\times3 = 15\) square feet.

Step2: Calculate the area of the two longer sides

The area of each longer side is length × height. There are two longer sides, so \(2\times(5\times1)=10\) square feet.

Step3: Calculate the area of the two shorter sides

The area of each shorter side is width × height. There are two shorter sides, so \(2\times(3\times1) = 6\) square feet.

Step4: Sum up the areas

Add the areas of the top, longer sides, and shorter sides: \(15 + 10+6=31\) square feet.

Answer:
