Question

What value goes in cell B?

Answer 1

A. 27

B. 125

C. 857
`(3)/(8)`

D. s³

Explanation:

The volume of the cube = side × side × side = (side)³

Let us use this rule to complete the table

A.

∵ The side length of the cube = 3 units

∴ Its volume = 3 × 3 × 3 = 3³

∴ Its volume = 27 unit³

B.

∵ The side length of the cube = 5 units

∴ Its volume = 5 × 5 × 5 = 5³

∴ Its volume = 125 unit³

C.

∵ The side length of the cube = 9
`(1)/(2)` units

∴ Its volume = 9
`(1)/(2)` × 9
`(1)/(2)` × 9
`(1)/(2)` = (9
`(1)/(2)`)³

∴ Its volume = 857
`(3)/(8)` unit³

D.

∵ The side length of the cube = s units

∴ Its volume = s × s × s = s³

∴ Its volume = s³ unit³
