What tool is used to measure the volume of an object?
Graduated Cylinder
Why is it important to know the volume of an object?
Finding the volume of an object can help us to determine the amount required to fill that object, like the amount of water needed to fill a bottle, an aquarium or a water tank. The volume of an object is measured in cubic units such as cubic centimeters, cubic inch, cubic foot, cubic meter, etc.
What is measuring volume?
Volume is the quantity of three-dimensional space enclosed by a closed surface, for example, the space that a substance (solid, liquid, gas, or plasma) or shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.
How do you find the area and volume of a different shape?
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
What is the formula for volume of a prism?
The formula for the volume of a prism is V=Bh , where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 9 cm and the width is 7 cm.
How do u find the volume of a pentagonal prism?
Calculating the Volume of a Regular Pentagonal Prism. Write the formula for finding the volume of a regular pentagonal prism. The formula is V = [1/2 x 5 x side x apothem] x height of the prism.
How do you find the surface area and volume of a pentagonal prism?
Volume of pentagonal prism= (5/2)×a×b×h cubic units
- a = Apothem length of the pentagonal prism.
- b = Base length of the pentagonal prism.
- h = Height of the pentagonal prism.
How do u find the area of a pentagonal?
Using a Formula. Area of a regular pentagon = pa/2, where p = the perimeter and a = the apothem. If you don’t know the perimeter, calculate it from the side length: p = 5s, where s is the side length.
How do you find the Apothem?
As long as the length of the sides is known, the apothem can be determined by using the formula: apothem= s/2 tan (180/n). In this formula, “s” is the length of the sides and “n” is the number of sides. If the sides of the heptagon are 7, for example, the formula would be filled out as apothem=7/2 tan(180/7).
Is the Apothem the same as the radius?
The apothem of a regular polygon is a segment connecting the center of the polygon to a midpoint of one of the sides, and the radius of a regular polygon is a segment connecting the center of the polygon to one of the vertices. The area of a regular polygon is ans2, or one half the product of the apothem and perimeter.
How do you find the area of Apothem?
You also learned the formula for finding the area of any regular polygon if you know the length of one side and the apothem: A = (n × s × a)2 A = ( n × s × a ) 2 , where n is the number of sides, s is the length of one side, and a is the apothem.
Is the Apothem equal to the side?
For an equilateral triangle, the apothem is equivalent to the line segment from the midpoint of a side to any of the triangle’s centers, since an equilateral triangle’s centers coincide as a consequence of the definition.
