Question

What is the surface area of prism below?

Answer 1

Answer:

240 cm^2

Step-by-step explanation:

Comment

There are 2 ends that are in the shape of a triangle

There is 1 base that is rectangular

There are 2 roof tops that are rectangular in shape.

Find the area of the triangles, base, 2 roof parts.

Solution

1 base

w = 4 cm

L = 12 cm

Area = L*w

Area = 12*4

Area =                                             48 cm^2

Two Triangles

B = 4 cm

H = 6 cm

Area = 1/2 b * h

Area = 1/2 6 * 4

Area = 12 cm

But there are 2 triangles

Area 2 triangles                              24 cm^2

Two roof tops

L = 12 cm

w = 7 cm          

Area = L*w for one roof top        

Area = 12*7 cm                                

Area = 84 cm^2

But there are 2 of them                  168 cm^2

Total Area                                        240  cm^2

Answer 2

Answer:

The surface area of a prism is given as S = (2 × Base Area) + (Base perimeter × height) where S represent the surface area

Step-by-step explanation:

2x48+32x6

96+32x6

=768

if I am right mark it as brainliest and if I am not then we all learn everyday I am just glad I did my best
