Perimeter of one face of the cube = 20 cm So, each edge of the cube = 20/4= 5 cm So, volume of cube = 5^3 = 125 cc. So, weight of tge cube = 125*8.25 = 1031.25 gm

Given perimeter of one face of a wooden cube is 20cm 4×side(s)=20cm Side=20/4=5cm Now volume of wooden cube is s×s×s=5×5×5=125cm^3 Weight of wooden cube is 125×8.25=1031.25 cm^3

Perimeter of one face of wooden cube=20cm. Therefore measure of each side of the cube 20/4 = 5cm. Therefore the volume of wooden cube =5^3 (five cube) =125 cc. So, weight of the wooden cube = 125 X 8.25 = 1031.25 gm = 1.03125 kg

Perimeter of one face of wooden cube=20cm. [formula: measure of each side of square = perimeter / 4] Therefore measure of each side of the cube 20/4 = 5cm. [formula of volume of a cube = side ^3] Therefore the volume of wooden cube =5^3 (five cube) =125 cc. [formula: total weight = weight per cc. X volume of cube] So, weight of the wooden cube = 125 X 8.25 = 1031.25 gm = 1.03125 kg read less

Perimeter of a cube with side a = 12 *a = 20cm Therefore , a = 5/3 cm Now , volume of cube = a^3 = (5/3)^3 = 125/27 cm3 If weight of 1cm3 is 8.25g Then weight of 125/27 cm3 will be = 8.25 * 125/27 gm = 38.19gm (ans)
