Find The Total Surface Area Of This Triangular Prism 18 Cm 30 Cm 24 Cm 7 Cm class=

Sagot :

Answer:

Step-by-step explanation:

Solution

Back  (This is a rectangle)

Area = w * h

w = 7

h = 18

Area = 7 * 18 =                                                          126 cm^2

Front and Back

Area = 1/2 * B * H  (This is a triangle -- There are 2 of them)

Givens

B = 24

h = 18

Area = 1/2 * 24 * 18

Area = 216

But there are two such triangles = 2*216 =             432 cm ^2

Ramp

Formula Area = L*w (This is a rectangle)

L = 30

W = 7

Area = 30 * 7  =                                                          210 cm^2

Total

210 cm^2

432 cm^2

126  cm^2

768  cm^2
