The surface area is 403.44cm2
SA = area of all sides added up. 6 Faces on a cube. 82 = 64. 64 x 6 = 384 The surface area of an 8" cube is 384"
Surface area = 4*pi*82 = 804.248 square feet rounded to 3 dp
Surface Area = 804.24772 units2
450 mm2 Ratio of areas is the square of the ratio of lengths. Ratio of volumes is the cube of the ratios of lengths. If the volumes are in the ratio of 512 to 3375, then the lengths are in the ratio of: 3√512 : 3√3375 = 8 : 15 ⇒ ratios of areas: 82 : 152 = 64 : 225 ⇒ as smaller has surface area of 128 mm2, the larger has: surface_area = (128 ÷ 64) x 225 mm2 = 450 mm2
83=512 82=64
Volume equals 512 then the cube root of this is 8 Solve by using Pythagoras' therom: 82+82 = 128 and the square root of this is 11.3137085 cm (the exterior diagonal) 82+11.31370852 = 192 and the square root of this is 13.85640646 cm (the interior diagonal)
Area = 5,281.02 inches2
