Volume of Composite 3D Figures Quick Check 5 of 55 of 5 Items Question Use the image to answer the question. What is the volume of the desk? (1 point) Responses 8,640 in.3 8,640 in. cubed 5,040 in.3 5,040 in. cubed 5,760 in.3 5,760 in. cubed 7,200 in.3
To find the volume of the desk, we need to calculate the volume of each individual shape and then add them together.
First, let's find the volume of the rectangular prism on the bottom of the desk:
Volume = length x width x height
Volume = 120 in x 30 in x 1.5 in
Volume = 5400 in^3
Next, let's find the volume of the rectangular prism on top of the desk:
Volume = length x width x height
Volume = 120 in x 30 in x 0.5 in
Volume = 1800 in^3
Now, we add the volumes together to get the total volume of the desk:
5400 in^3 + 1800 in^3 = 7200 in^3
Therefore, the volume of the desk is 7,200 in^3.
