Question

The lateral area of the right regular triangular prism is 18 cm^2. Give your answer in decimal form rounded to 2 decimal places.

Answer 1

find the area of the 3 rectangular faces.

1 face is

\[Area = 3 \times x= 3x\]

so then the sum of the 3 areas = 18 or

3x + 3x + 3x = 18

now you can solve for x

Answer 2

I got 2 for x. I just need the total surface area now.

Answer 3

that makes sense to me

Answer 4

ok... so for the surface area you need to find the height of the triangles .



double to answer and add it to the lateral area of 18.

hope it helps
