Find the S.A of all the cubes and then add them together.

S.A = 6a²

a is the side length

S.A = 6(3)² = 54
S.A = 6(2)² = 24
S.A = 6(1)² = 6

Now add them all together.

54 + 24 + 6 = 84

So the total surface area is 84

Hope this helps :)

Step-by-step explanation:

I'm not sure if you're supposed to reuse the same numbers just in a different Three digit number. Or if you're supposed to use the number one time and one time only. But if not here's there's some numbers that you could use

He basically all You have to do Is take the numbers and turning them into three digit numbers Without repetition.

If 5 ibs apples cost $2.99, how much would 3 ibs cost?
AnnZ [28]

We know that 5 lbs of apples cost $2.99

To know how much do 3 lbs of apple cost, you can use cross multiplication

If 5 lbs cost $2.99

Then 3 lbs cost $x

The proportion between the price and the number of apples is the same, you have to calculate it as:

\begin{gathered} \frac{2.99}{5}=\frac{x}{3} \\ (\frac{2.99}{5})\cdot3=x \\ x=1.794 \end{gathered}

3 lbs of apples cost $1.79
