well, what we need to know is what the height is, so we know we have a width of 5 ft. , a length of 10 ft. , and we know the area aka volume is 126 ft2. (squared ft.) so we multiply 5ft. by 10ft. which gets us 50 ft. But we need to add on 126 squared ft.) that gives us 176 ft2. so the amount is 176 ft2! Hope this helped you :)
