Answer:
96cm
Step-by-step explanation:
For a triangular prism we find the surface area by doing base times height/ length times width, but since we have a triangle we would have to divide the answer we get by 2. Once we get all the sides we then would have to add them all up.
<h3>front back top </h3>
3X4X1/2 ( HINT: ITS THE SAME AS THE FRONT) 7X5
12X1/2 6= back 35= top
6= front
<h3>Bottom side <u><em>
since we are done finding all</em></u> </h3>
7X4 3X7 <em><u>of the area of the shapes we add </u></em>
28= bottom 21= side <u><em>all of them together.</em></u>
Surface area= 6+6+35+28+21= <u><em>96 cm</em></u>
Answer: w = 7, x = 6
Step-by-step explanation: Solve by substitution
W + b = 13
rewrite as b = 13 - w and substitute that value for b in the second equation
6.5w + 2b = 57.5 Then solve for w
6.5w + 2(13-w) = 57.5 . Distribute
6.5w + 26 - 2w = 57.5 . Subtract 26 from both sides. Combine like terms and simplify
6.5w - 2w = 57.5 - 26
4.5w = 31.5 Divide both sides by 4.65
w = 7 . Substitute 7 for w in the first equation and solve for b
7 + b = 13 . Subtract 7 from both sides
b = 6
