1.	For constructing a square pyramid, Rabiya cut of four triangles and a square. Figure given below shows the measures of these triangles and square. Can you make a square pyramid by using these measures? Explain the reason.
Answer» Base edge = 42 cm Slant edge = 29 cm Slant height = \(\sqrt{29^2-(\frac{42}{2})^2}\) = \(\sqrt{29^2-21^2}\) = \(\sqrt{841-441}\) = \(\sqrt{400}\) = 20 cm Slant height is less than the half of the base edge 21 cm so not possible for making a square pyramid

For constructing a square pyramid, Rabiya cut of four triangles and a square. Figure given below shows the measures of these triangles and square. Can you make a square pyramid by using these measures? Explain the reason.

Answer»

Base edge = 42 cm

Slant edge = 29 cm

Slant height = \(\sqrt{29^2-(\frac{42}{2})^2}\)

= \(\sqrt{29^2-21^2}\)

= \(\sqrt{841-441}\)

= \(\sqrt{400}\)

= 20 cm

Slant height is less than the half of the base edge 21 cm so not possible for making a square pyramid
