The answer I got was B can you also provide step by step explanation

Step-by-step explanation:

Start by finding the volume of the bottom part of the doghouse.

Use the equation:

Volume = Height × Length × Width.

Then. plug in the corresponding values:

Volume = 3.0Ft × 4.5ft × 4.5ft

multiply the values:

Volume = 60.75Cubic feet

Now, let's find the value of the top part of the doghouse: The roof

to do this, We find the area of the triangle shape on the side and multiply that by the length of the roof.

Use the equation for finding the area of a triangle:

Area = Base × Height / 2

We plug in the values:

Area = 4.5ft × 1.5ft / 2

We solve the equation:

Area = 6.75 /2

Area = 3.375

Now to the next step to get the volume of the roof, We multiply this by the length of the roof.

Volume = 3.375 × 4.5

Volume = 15.1875

Finally we add the volume do the roof and the bottom part to find the full area of the doghouse.

60.75 + 15.1875

Sum them up:

75.9375

That's the volume!

So the answer is D!

Sorry you got B. This is how to solve it, If you are confused or don't understand send me a chat or reply to my answer.
