Answer:
174 CM²
Step-by-step explanation:
First we split up the triangular prism into shapes we can better understand (2 triangles, and 2 rectangles)
We solve the area of the triangles by using the formula to the area of a triangle (B·H÷2) 8·6÷2=24
There are 2 triangles therefore we get 2*24 which is 48 CM²
Now we calculate the area of the rectangles (7·10=70, 8·7=56)
Finally we add up all the numbers (70+56+48=174 CM²)
Therefore the surface area of the triangular prism is 174 CM², respectively.
Answer:
Volume = 502.65 cm³
Step-by-step explanation:
V= 3.14×4²×10 = 502.65 cm³
L + F + G = 51
F = 3L...F = 3(G + 4)....F = 3G + 12
L = G + 4
(G + 4) + (3G + 12) + G = 51
5G + 16 = 51
5G = 51 - 16
5G = 35
G = 35/5
G = 7 <=== Greg sold 7
L = G + 4...L = 7 + 4....L = 11 <== Lin sold 11
F = 3G + 12.....F = 3(7) + 21....F = 21 + 12....F = 33 <== Fran sold 33
