The surface area of the triangular prism pictured below is 204 square centimeters. What is the height of the prism?

height x=21.5cm

Step-by-step explanation:

Surface area = 2+ area of triangles + area of the 3 rectangles

SA = 204

204 = 4*3 + x*5 + 5*4 + x*3

204 = 12 +20 +8x

204 -12-20 = 8x

172/8 = x

21.5 = x

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380
