Answer: Volume = 60in^3, Surface Area=104in^2

Explanation:

For volume you multiply =5 x 2 x 6, b/c the formula is length x width x height. The for surface area you want to find the area of all sides of the object. So first we start off with front and back, which is just 6 x 5 for one side, giving us 30 for the front and 30 for the back. Then we calculate the sides which are 6 x 2, giving us 12 for each size. lastly its the top and bottom, so it would be 2 x 5 giving us 10 for the top and10 for the bottom. Finally we add all of our values so 30 + 30 + 12 +12 +10 + 10 which gives us 104 in^2

Hope this helps :D
