Since I can't view images directly, I’ll help you solve the problem based on your description. Please provide the dimensions of the composite figures (e.g., length, width, height of each prism) so I can calculate the volumes.
However, if you're referring to a standard problem like this, here's how to approach it:
---
Problem: Find the volume of the composite figure.
A composite figure is made up of two or more basic 3D shapes (like rectangular prisms). To find the total volume, calculate the volume of each individual part and then add them together.
---
General Formula:
Volume of a rectangular prism =
Length × Width × Height
---
Let’s assume the image shows two problems with composite solids made of two rectangular prisms labeled A and B.

Problem 1:
Suppose the figure has:
-
Prism A: 2 cm (length), 3 cm (width), 2 cm (height)
-
Prism B: 5 cm (length), 3 cm (width), 2 cm (height)
#### a) Volume of Prism A:
= 2 × 3 × 2 =
12 cubic cm
#### b) Volume of Prism B:
= 5 × 3 × 2 =
30 cubic cm
#### c) Volume of the solid:
= 12 + 30 =
42 cubic cm
---
Problem 2:
Suppose the figure has:
-
Prism A: 6 ft (height), 4 ft (width), 4 ft (depth) — but only half of it might be stacked
-
Prism B: 8 ft (length), 4 ft (width), 2 ft (height)
But wait — if it's a composite shape, let's say:
-
Prism A is a cube-like block on top: 4 ft × 4 ft × 6 ft
-
Prism B is the base: 8 ft × 4 ft × 2 ft
Wait — that doesn’t make sense because the height would overlap.
Let’s assume a typical configuration:
-
Prism A: 4 ft (length), 4 ft (width), 6 ft (height) — on top
-
Prism B: 8 ft (length), 4 ft (width), 2 ft (height) — below
But the 4 ft width matches, so maybe the total length is 8 ft?
Alternatively, suppose:
-
Prism A: 4 ft × 4 ft × 6 ft = 96 ft³
-
Prism B: 8 ft × 4 ft × 2 ft = 64 ft³
But they may share a common base.
Wait — perhaps the figure is like:
- Bottom prism (B): 8 ft long, 4 ft wide, 2 ft high
- Top prism (A): 4 ft long, 4 ft wide, 6 ft high — placed on top of the left side
Then:
#### a) Volume of Prism A:
= 4 × 4 × 6 =
96 cubic ft
#### b) Volume of Prism B:
= 8 × 4 × 2 =
64 cubic ft
#### c) Volume of the solid:
= 96 + 64 =
160 cubic ft

But since I don’t have the actual image, I need you to confirm the dimensions.
Please reply with the exact measurements from the image, such as:
- For Figure 1:
- Prism A: L= ?, W= ?, H= ?
- Prism B: L= ?, W= ?, H= ?
And same for Figure 2.
Once I have those, I’ll give you the correct answer step by step.
