What is the cube root of 72? - vedantu.com
WebMar 26, 2016 · Example 1: Factor the difference between the cubes, 216 – 125. Use the difference of cubes rule to find the variables. The cube root of 216 is 6, and the cube root of 125 is 5; so 6 is the a, and 5 is the b. Substitute the values into the equation. 216 – 125 = (6 – 5) (36 + 30 + 25). WebMar 21, 2024 · To find the cube root of 72, now we can rewrite the 72 in the cube root form, where = 72 3 Since the number 72 is not a perfect cubic number. So now we can separate the number 72 that is, = 8 × 9 3 where the multiplication of 8 × 9 = 72 Since looking for the perfect cube number, here 8 is perfect cube number so, = 2 3 × 3 2 3 WebVolume of the Cube = 125 in 3 = a 3 ⇒ a 3 = 125 Cube rooting on both sides, ⇒ a = ∛125 in Since the cube root of 125 is 5, therefore, the length of the side of the cube is 5 in. Example 3: Find the real root of the equation x3 − 125 = 0. Solution: x 3 − 125 = 0 i.e. x 3 = 125 Solving for x gives us, iowa city va directory
