What will be the base of a square pyramid?

How many vertices does a cone have?

Here, you find four nets. There are two correct nets among them to make a tetrahedron. See if you can work out, which nets will make a tetrahedron

Which figure will be formed by folding the net shown below?

The following diagrams show the nets of various solids. Name the solids.

Draw the figure of cross-section obtained by cutting vertically the following shape of cylinder

Can this be a net for a die? Explain your answer

Fill the correct symbol >, =, < in the following blanks.
(a) Faces of pyramid ----- Vertices of the pyramid.
(b) Faces of pyramid -----  Edge of the base
(c Edges on the base of a tetrahedron ------ Faces of a tetrahedron.

Draw the net of a square pyramid with base as square of side 4 cm and slant edges 6 cm.

Which of the following nets is a net of a cylinder?

Take a square piece of paper as shown in fig. (i). Fold it along its diagonals as shown in fig. (ii). Again, fold it as shown in fig. (iii). Imagine that you have cut-off 3 pieces of the form of congruent isosceles right-angled triangles out of it as shown in figure 4

When we cut a corner of a cube as shown in the figure, we get the cut-out piece as
