Volume of the cube = Volume of water displaced
x³ = 50 x 36 x 15
x³ = 27000
∛x³ = ∛27000
x = 30
The cube has 6 surfaces ∴ the total surface area = area of one surface x 6
∴ Total surface area = 30 x 30 x 6 = 5400 cm²
x³ = 50 x 36 x 15
x³ = 27000
∛x³ = ∛27000
x = 30
The cube has 6 surfaces ∴ the total surface area = area of one surface x 6
∴ Total surface area = 30 x 30 x 6 = 5400 cm²
