Select the correct answerA cube has a total surface area of 864 cm². Find the length of one edge of the cube.Options18 cm16 cm12 cm14 cm
Question
Solution 1
A cube has 6 equal sides. So, to find the area of one side, we divide the total surface area by 6.
864 cm² ÷ 6 = 144 cm²
The area of one side of a cube is also calculated by squaring the length of one edge. So, to find the length of one edge, we take the square root of the area of one side.
