A should be the correct answer. As you can see, the cubes on the lowest level is 1 cube. The second level is equal to 2 cubes and the highest level is equal to 3 cubes

Answer:</h3>
a=45
<h3>
Solution:</h3>
- We need to multiply both sides by 3 in order to get rid of the denominator, 3:
- 2/3a•3=30•3
- 2a=90
- Divide both sides by 2:
- a=45
Hope it helps.

Proofs can be tricky! What helps me is thinking through them step by step and how I would prove I did something. While I'm not entirely sure what options you have for this proof, I've given my best guess.
Hope this helps!! :)
The surface area would be :
A = 4 (1/2 x b x h) + (l x b)
A = 4 ( 1/2 x 42 x 35) + (42 x 42)
A = 4704 cm squared
