Lateral surface area = (23×12.04)+(23×8)+(23×9)
= 276.92 + 184 + 207
=667.92
= 668m²
Total surface area = 668 + 1/2(2×8×9)
= 668 + 72
= 740m²

Step-by-step explanation:
Answer:
0.3 galloons of water.
Step-by-step explanation:
We know that 1/5 galloons of water fills 2/3 of the bin.
So, we can write the following fraction:

We want to find how many galloons will fill the entire bin or 1 whole bin. So, we can write the following proportion:

To find our answer, we need to solve for x.
So, let's cross-multiply. This yields:

Multiply both sides by 3:

The left side simplifies. Multiply on the right:

Now, multiply both sides by 1/2:

Simplify the left. Multiply on the right:

So, 3/10 of 0.3 of a gallon of water will fill the entire bin.
And we're done!
X + (4x+15) = 180
5x+15=180
5x=165
x=33
4(33)+15=147. (Or you could subtract 33 from 180)
Check answer: 33+147=180 yes
