This sculpture designed by Mr. Newman’s colleague, Tia, is shaped like a hollow triangular pyramid. All 3 of the lateral faces are 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

What is the area of each of the lateral faces?  

✔ 12

m²

What is the total lateral area of the sculpture?  

✔ 36

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.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide
