A cube has a side of length 2.342m. Find volume and surface area in correct significant figures.

Answer

A, B, C, D

Explanation

`V= a^3 = (2.342 m)^3 = 12.84578569 m^3`
`= 12.85 m^3` (rounding off to four significant digits )
`S = a^2 = (2.342)^2 m^2 = 5.484964 m^2 `
`=5.485 m^2` (rounding off to four significant digits)
