Question

Given that the surface area of a cube is given by the formula SA=6s2, what is the value of SA if s=1/2 cm?
A.1 cm2
B.3 cm2
C.1/2 cm2
D.1 1/2 cm2

Answer 1

I think the answer is A

Answer 2

So you have the equation:

\(\bf{SA=6(\frac{1}{2})^{2}}\)

First you would apply the exponent. Since it is a fraction you raise the denominator by the exponent.

\(\bf\large{\frac{1}{2^{2}} = \frac{1}{4}}\)

In which you multiply by 6.

\(\large\bf\color{red}{6 \times \frac{1}{4}}\)

Answer 3

so the answer is 1 1/2

Answer 4

Correct.
