This sculpture designed by Mr. Newman’s colleague, Tia, is shaped like a hollow triangular pyramid. All 3 of the lateral faces a
re congruent and made of glass. How much glass was used to make the sculpture, if each face has a base length of 4 m and a slant height of 6 m? A triangular pyramid. The triangles have a base of 4 meters and height of 6 meters.
What is the area of each of the lateral faces? ____ m²
What is the total lateral area of the sculpture? ____ m²
Step-by-step explanation: I forgot the "each of the lateral faces", but the total lateral area is 36 m² because there are there lateral faces, and the are of each of the lateral faces is 12 m².
Explanation: AB is approximately equal to DE. BC is equal to EF and angle ACB is approximately equal to angle DEF, therefore triangle ABC is approximately equal to triangle DEF.
