Answer 1

Answer:

A square of side 5 centimetres and four isosceles triangles, each of one side 5 centimetres and the height to the opposite vertex 8 centimetres; these are to be joined to make a square pyramind. How much paper is needed for the job?

ANSWER:

Side of the square = 5 cm

Base of the isosceles triangle = 5 cm

Height of the isosceles triangle = 8 cm

Area of the square = (side)2 = (5 cm)2 = 25 cm2

Area of one isosceles triangle =

Area of four isosceles triangles = 20 × 4 cm2 = 80 cm2

Area of the square pyramid = Area of the square + Area of four isosceles triangles

= (25 + 80) cm2

= 105 cm2

Thus, we need 105 cm2 paper for the job.
