text: if those are the dimensions, then it is not a cube. a cube has equal dimensions all the way around:\n\nbase = length = height \n\nthis is a rectangular prism\n\nvolume = base * height * length\n\nvolume = 6 * 4 * 2\n\nvolume = 48 cubic inches\n\n\nthe surface area would be the area of the six rectangles that make up the "skin" of the prism.\n\ntwo rectangles will have an area of: 6 * 4 = 24\ntwo rectangles will have an area of: 4 * 2 = 8\ntwo rectangles will have an area of: 2 * 6 = 12\n\ntherefore the total surface area will be:\n\n= 2(24) + 2(8) + 2(12)\n= 48 + 16 + 24\n= 88 square inches
