The surface area of the right triangular prism is 270 sq ft
<h3>Total surface ara of the prism</h3>
The total surface area of the prism is the sum of all the area of its faces
For the two triangles
A = 2(0.5bh)
A = bh
A = 7 * 12 = 84 sq.ft
For the two rectangles
A = 2lw
A = 2(6*12)
A = 2 * 72 = 144 sq.ft
For the third triangle;
Area 6ft * 7ft
Area = 42 sq.feet
Taking the sum of the areas
TSA = 84 + 144 + 42
TSA = 270 sq ft
Hence the surface area of the right triangular prism is 270 sq ft

Answer: the answer to (g+h)x4 is
4g+4h
Step-by-step explanation:
(g+h)x4
multiply the parentheses by 4
and that will give you 4g+4h
sorry if it was wrong
= 19 this is the answer I'm guessing since 16-12= 4 so 16 is 4 more than 12
B, because to substitute for a variable you have to have an equation to substitute first.
