How can measure the volume of irregular shape??
Answers
Answer:
Explanation:
You can calculate the volume of irregular shapes easily once you know how to get the volume of a single three-dimensional shape .
A house
The house above is made of two 3-d shapes: A triangular prism and a rectangular prism
The roof of the house is the one shaped like a triangular prism
Volume of house = volume of triangular prism + volume of rectangular prism
volume of triangular prism = area of triangle × length of house
volume of triangular prism =
base of triangle × height of triangle2
× length of house
length of house = 50 feet, base of triangle = 15 feet, and height of triangle = 10 feet
volume of triangular prism =
15 × 102
× 50
volume of triangular prism = 75 × 50 = 3750 feet3
volume of rectangular prism = 15 × 15 × 50 = 11250 feet3
Volume of house = 3750 + 11250 = 15000 feet3
Ice cream cone:
When you order ice cream, you may have never realized that it could be a combination of half a sphere and a cone
Of course, we have to assume that the shape made by the ice cream scoop is half a sphere.
The shape of my ice cream shown below is half a sphere and then we put it on a cone. What is the volume?
It may be easier to see how to compute the volume if we remove the ice cream
Pretend that the radius of the cone or r is 1.5 inches and the height of the cone or h is 6.5 inches here is how to compute the volume
Volume = volume of half the sphere + volume of the cone
volume of a sphere =
4 × π × r33
volume of a sphere =
42.393
volume = 14.13 inches3
Since it is half a sphere, we get 7.065 inches3
volume of a cone =
π × r2 × h3
volume of a cone =
3.14 × 1.52 × 6.53
volume of a cone =
45.92253
volume of cone = 15.3075 inches3
volume of the whole thing is 7.065 + 15.3075 = 22.3725 inches3
A box has 4 identical ice cream cones arranged inside of the box as shown below. The radius of the base of the cone is 1 inch and the height is 6 inches
What is the volume of the space left inside the box ?
Space left inside the box = volume of box - volume of 4 cones
Volume of box = 8 × 8 × 8 = 512 inches3
volume of a cone =
π × r2 × h3
volume of a cone =
3.14 × 12 × 63
volume of a cone = 6.28. Therefore, volume of 4 cones = 4 × 6.28 = 25.12
Volume left inside = 512 - 25.12 = 486.88 inches3
Hopefully you know now how to find the volume of irregular shapes!
