Alexander Graham Bell, the inventor of the telephone, also invented a kite made out of "cells' shaped like triangular pyramids. A kite is made out of triangular pyramids with fabric covering one face and the base of the pyramid. The face and base both have heights of 17.3 cm and side lengths of 20 cm. How much fabric is needed to make each pyramid cell for the kite?

The fabric needed for each pyramid cell of the kite will have an area of 173 cm².

Step-by-step explanation:

Area of a face of the triangular pyramids = (1/2)(b)(h)

where

b = base of a triangle of the triangular pyramid = 20 cm

h = height of each triangle of the triangular pyramids = 17.3 cm

Area = (1/2)(20)(17.3) = 173 cm²

Just like the image presented with the question, each face of the pyramid that has a cell of fabric has only one, So, the fabric needed for each pyramid cell of the kite will have an area of 173 cm².

Hope this Helps!!!

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
