Sketch the 3D figures of the following objects and also sketch their front, side and top views.

Name the hidden faces in the following solid cuboid, when observers eye is just in front of face $\mathrm{ABCD}$.

The dimensions of a cuboid are shown in the following figure, i.e., $\mathrm{BC}=5 \mathrm{cm}, \mathrm{CD}=3 \mathrm{cm}, \mathrm{GC}=2 \mathrm{cm}$.

Draw the cuboid with its dimension as it looks from top (top view), side (side view) and front (front view).

On the net of a cube, fill the plane with the numbers $1, 2, 3, 4, 5 \mathrm{and} 6$, such that the opposite faces have a sum of $7$.

Verify the Euler's formula for the following Cube

Draw the net of a cube and fill the places with the numbers $3, 4, 5, 6, 7, 8$, such that sum of the opposite faces becomes $11$.

When a cube is represented in 2-D, how many faces are shown as hidden faces?

Two cones of equal shape and height are placed together such that one of them is vertically opposite , i.e., upside down. What shape does this combination form?

What shape will you get, if you place three cubes each of side $2 \mathrm{cm}$ together in the same place? Write the dimensions also.
