Worksheet for identifying front, side, and plan elevations of 3D shapes.

To solve the problem, we need to determine the front elevation, side elevation, and plan elevation for each of the 3D objects shown in the image. Let's analyze each object step by step.

Object 1:

#### Description:
- The 3D object consists of three cubes arranged as follows:
- One cube is on the left.
- One cube is on the right.
- One cube is stacked on top of the left cube.

#### Front Elevation:
- From the front view, we see two cubes in a row (left and right) with one cube stacked on top of the left cube.
- The front elevation will have two rows:
- The top row has one cube.
- The bottom row has two cubes.

#### Side Elevation:
- From the side view, we see two cubes stacked vertically.
- The side elevation will have two rows:
- Both rows have one cube.

#### Plan Elevation:
- From the top view, we see three cubes in a row (left, middle, and right).
- The plan elevation will have one row with three cubes.

#### Final Answer for Object 1:
- Front Elevation:
```
o
oo
```
- Side Elevation:
```
o
o
```
- Plan Elevation:
```
ooo
```

Object 2:

#### Description:
- The 3D object consists of four cubes arranged as follows:
- Two cubes are stacked vertically on the left.
- Two cubes are stacked vertically on the right.

#### Front Elevation:
- From the front view, we see two columns of cubes:
- The left column has two cubes stacked vertically.
- The right column has two cubes stacked vertically.
- The front elevation will have two rows:
- Both rows have two cubes.

#### Side Elevation:
- From the side view, we see two cubes stacked vertically.
- The side elevation will have two rows:
- Both rows have one cube.

#### Plan Elevation:
- From the top view, we see four cubes arranged in a 2x2 grid.
- The plan elevation will have two rows with two cubes each.

#### Final Answer for Object 2:
- Front Elevation:
```
oo
oo
```
- Side Elevation:
```
o
o
```
- Plan Elevation:
```
oo
oo
```

Object 3:

#### Description:
- The 3D object consists of four cubes arranged as follows:
- Three cubes form a "T" shape on the base.
- One cube is stacked on top of the middle cube of the "T" shape.

#### Front Elevation:
- From the front view, we see three cubes in a row (left, middle, and right) with one cube stacked on top of the middle cube.
- The front elevation will have two rows:
- The top row has one cube.
- The bottom row has three cubes.

#### Side Elevation:
- From the side view, we see two cubes stacked vertically.
- The side elevation will have two rows:
- Both rows have one cube.

#### Plan Elevation:
- From the top view, we see four cubes arranged in a "T" shape.
- The plan elevation will have two rows:
- The top row has one cube.
- The bottom row has three cubes.

#### Final Answer for Object 3:
- Front Elevation:
```
o
ooo
```
- Side Elevation:
```
o
o
```
- Plan Elevation:
```
o
ooo
```
