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=81.6in³
Answer:
The first option...1/3^3
Step-by-step explanation:
3^2 × 3^-5
= 3^2 × 1/3^5
= 3^2 / 3^5
= 3^2 - 5
= 3^-3
= 1 / 3^3...option A
The slope in fraction form is -9/4 so converted to a decimal is -2.25
