Answer:
<u>The volume of the prism is 97.2 m³</u>
Step-by-step explanation:
Let's recall that the volume of a triangular prism is base * height and the base is a triangle, then the formula is as follows:
Volume = 1/2 (base of the triangle * height of the triangle) * height of the prism
Replacing with the real values, we have:
Volume = 1/2 (7.2 * 9) * 3
Volume = 32.4 * 3 = 97.2 m³
<u>The volume of the prism is 97.2 m³</u>
Donc pour trouver la réduction de 30% nous allons trouver 30% de 49 alors nous allons faire 30 × 100 × 49 = 14,7 14,7 est la réduction maintenant nous devons faire 49 € -14,7 € soit 34,3 €, le prix est maintenant de 34,3 €, désolé d'utiliser Google Translate pour vous aider, mais j'espère que c'est correct :)
STEP 1:
find the length of the sides of the square
AREA FORMULA (for a square)
x= side
A=x^2
225=x^2
take square root of both sides
15 feet= x
STEP 2:
find perimeter
PERIMETER FORMULA (for a square)
x= side of square
P= 4x
use x value from step 1
P= 4(15 ft)
P= 60 feet
ANSWER: The perimeter is 60 feet.
Hope this helps! :)
Answer:
Euclid
