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
Step-by-step explanation:
We are given with the two sides of a right angled triangle having lengths of 5 and 13. It is required to find the length of the third side of a right triangle. We know that hypotenuse of right angled triangle is the longest side.
For right angle triangle, we use Pythagoras theorem as :
H²=P²+B²
P is perpendicular distance
B is base
Putting H = 13 and P = 5, then
B² = H²-P²
B² = (13)²-(5)²
B²=144
B=12
So, the length if the third side of a right triangle is 12. It is the only solution.
