Question

The children’s museum has a large fish tank with the dimensions shown. The tank does NOT have a cover. What is the surface area of the fish tank?

Answer 1

Answer:

The surface area of the fish tank is:

                          230 square feet

Step-by-step explanation:

Let  l denote the length of tank

and w denote the width of the tank

and h denote the height of the tank.

from the figure we have:

l=10 feet, w=5 feet and h=6 feet

Now, we need to find the surface area of tank such that the tank does not has a cover this means the top face is not there.

Hence, the surface area is calculated as follows:

$Surface\ Area=l\times w+2\times l\times h+2\times w\times h\\\\\\Surface\ Area=10\times 5+2\times 10\times 6+2\times 5\times 6\\\\\\Surface\ Area=50+120+60\\\\\\Surface\ Area=230\ \text{square\ feet}$

Answer 2

The answer is 230 square feet lol
