if asked to find area (in ft) of 10L, 5W, 8D,   is the formula 2LW + 2LD+2WD?   I got 340 sf

jim_thompson5910 · Answer

assuming the length is 10, the width is 5 and the depth is 8

and if this is a rectangular prism, then the final answer of 340 square feet is correct, so nice work (assuming those assumptions are correct)

anonymous · Answer

problem does not specify the shape, just find area and volume, given those dimensions.

jim_thompson5910 · Answer

hmm that's odd

jim_thompson5910 · Answer

so it doesn't say if it's a rectangular prism?

anonymous · Answer

no. just find area. and then find volume.

anonymous · Answer

so area of a rectangle is l x w, but if a depth is given, that would be a factor in determining the area?

jim_thompson5910 · Answer

yes you use all 3 dimensions to find the surface area

anonymous · Answer

would that still be in square ft though?
