My husband and I just used geometry the other day to estimate how much tile to buy for our 2 bathrooms.  Our bathrooms have a lot of irregular spaces, so we had to measure the entire perimeter of each bathroom.  We then split the bathrooms into different geometric shapes to find the area.  We had to work our formulas for several squares, rectangles, and triangles.   Then we added them all together to come up with the square footage.  After that, we had to estimate how many 12 inch by 12 inch tiles we needed.  It was pretty tricky, but my husband is a math whiz, so it's easy for him.  He's an engineer, go figure...

1 sq. inch = 0.0069444 sq. ft.   \nSo you multiply 363.9 x 0.0069444, and the total is 2.527 sq.ft

a cube has six sides: top, bottom, front, back, left and right.\n\nIf each edge is 12 inches (1 foot) then each side is 1foot by 1 foot\nso 1 square foot.\n\nThe total surface area is 6 square feet.

answer depends on arrangement.  \n\nSA = area of top + bottom + left side + right + front + back.\nif 1x1x24, SA = 24+24+24+24+1+1 = 98 sq cm, \nif 1x2x12, SA = 24+24+12+12+2+2 = 76 sq cm,\nif 1x3x8, SA = 24+24+8+8+3+3 = 70 sq cm,\nif 1x4x6, SA = 24+24+6+6+4+4 = 68 sq cm,\nif 2x2x6, SA = 12+12+12+12+4+4 = 56 sq cm,\nif 2x3x4, SA = 12+12+8+8+6+6 = 52 sq cm.\n\nnotice how the SA gets smaller as the arrangement becomes more compact.

Figure out how many square inches on the cube.  One side is 10" x 10" = 100 inches square.\n\n6 sides makes 600 inches square.\n\nA square foot is 12 x 12 inches = 144 inches square\n\nSquare footage is 600 / 144 = 4.17

Multiply the two numbers together, then divide that total by 144.\n\nsample:  12in. x 24in. = 288sq in.\n                288sq. in. / 144sq. in. = 2 sq ft.\n                 144 is the number of sq inches in a square foot
