We had to find the surface area of various rectangular prisms. I did most of them easily, but there are two that I need a little help with...
The first one is:
The length is 13m
The width is 5m
The height is 4m
So what is the surface area?
The second one (which is a bonus question) is:
Length = 5feet
Width = 3feet
Height = 9 INCHES

Just remember after reading the above link to convert the 9 inches to feet. that being 9/12 or exactly .75 feet
