Find the surface area of the triangular prism below?

10 divided by 3 = 3.33 for each side of the triangle.

2 x 6 = 12(area of two triangles)

10(height) x 3.33(area of one side of the triangle) x 3(three rectangles) = 99.9

Add given areas:

99.9 + 12 = 111.9 rounded = 112 cm^2

Please wait for more responses to be sure, thank you.

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
