If all of the dimensions of the tank are doubled, since we live in three dimensions, the volume of the new tank will be $2^3=8$ times as large. $8\cdot 2000=16000$ feet, or answer choice A. Hope this helps!

What’s the surface area

STALIN [3.7K]

Answer: 38 in.^{2}

Step-by-step explanation:

1/ Find the area of the triangular sides. (1/2 x 2 x 6 = $6 in.^{2}$ for each triangular side)

2/ Find the area of each of the rectangular sides. In this case, the bottom (base) side is 2x6 = $12 in^{2}$ . The rectangular side on the left is 2x3 = $6 in.^{2}$ , and the rectangular side on the right is 4x2 = $8 in.^{2}$ .

3/ Add everything together. Rectangular Sides + Triangular Sides = Surface Area ---> $12 in.^{2} + 6 in.^{2} + 8 in.^{2} + 6 in.^{2} + 6 in.^{2} = 38 in.^{2}$

4/ You have your answer, now hope it helps ! :)
