### How many square feet are in 7ft 2 inches long x 5ft 11 inches wide x 8ft 7 inches high?

Square feet measure area, you're looking for volume, which is cubic feet. 86 x 71 x 103 cubic inches. To get cubic feet divide by 1728 giving 363.96 cuft. If you're wanting to know the surface area of a solid with those dimensions then it is 2 x ((86 x 71) + (86 x 103) + (71 x 103)) ie 44554 sqin or 309.4 sqft

### How many 50 pound bags of sand do you need to fill a sandbox that is 86 inches long x 45 inches wide x 6 inches deep?

That depends on how many cubic feet of sand fit in that 50 pound bag. I can get you close, but cannot give the final answer.

### What is the measurement of the following area 215 feet by 172 feet by 86 feet by 342 feet?

It can be flexed into a rhombus which can be made so thin that its area is virtually zero!
