Answer:
7.
lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²
curved surface area=2[area oftraingle]=2×1/2×4×3
=12cm²
now
total surface area=72cm²+12cm²=84cm²
8.
volume of traingular prism=area of traingle ×length
=1/2×12×3.4×4=81.6cm³
Answer:
3x - y/2
Step-by-step explanation:
Answer:
3 with the exponent of four.
Step-by-step explanation:
You would count the number of of three's. Since there are four three's, then you would write the 4 right by the three on the top right hand corner.
Answer:
18x
Step-by-step explanation:
3x^2 - 27 = -18x
x^2 - 3x = -1x
-18x / -1x = 18x
3x^2 = 9
x^2 = 2x
The exact volume would be 80 feet long
