Question

Use the formula V=6s2 to find the surface area of a cube with the sides of length a = 1/3 cm

Answer 1

`V = (2)/(3) cm^2`

Explanation:

Given

`V = 6s^2`

Required

Find the surface area when the length is
`(1)/(3)\ cm`

To do this, we simply substitute
`(1)/(3)\ cm` for s in the given formula

`V = 6s^2` becomes

`V = 6 * (1)/(3)^2`

`V = 6 * (1)/(3) * (1)/(3)`

Combine Fractions

`V = (6 * 1 * 1)/(3 * 3)`

`V = (6)/(9)`

Simplify Fraction

`V = (2)/(3) cm^2`
