Answer:
First figure: 445 in³
Second figure: 224 in³
Third figure: 243 in³
Step-by-step explanation:
For all of these figures, we'll have to find the volume of each figure separately and then add them together to get the full volume. Don't worry, it's not that hard! :)
First figure:
First, find the volume of the square prism.
(Formula) V = b(base)²h(height) = 10² · 4
= 400
Second, find the volume of the small rectangular prism.
(Formula) V = width x height x length = 3 · 3 · 5
= 45
Answer = 400 + 45 = 445 in³
Second figure:
Here we just do the same thing. First, find the v of the rectangular prism.
(Formula) V = width x height x length = 8 · 2 · 12
= 192
Next, find the volume of the smaller rectangular prism.
(Formula) V = width x height x length = 2 · 2 · 8
= 32
Answer = 192 + 32 = 224 in³
Okay, by now, I'm sure you get it so I'm just going to give you the answer for the third one - I promise I did the same thing as in the first two steps (P.S. on the last figure, they're both square prisms, not rectangular prisms :)
216 + 27 = 243 in³
