Volume of a Rectangular Prism - 7th Grade Math

In this video, you will learn how to find the volume of a rectangular prism. Volume is how much space a three dimensional shape occupies. You will learn how to find the volume using the formula LxWxH. Length multiplied by width multiplied by height. A rectangular prism is a three dimensional shape which has 6 faces, 8 vertices, and 12 edges.

Area of Triangles - 7th Grade Math

This video explains how to find the area of triangles. The formula for finding the area of any triangle is 1/2xBxH. That means you have to multiply the base by the height and divide by two to get the area. The formula is the same for all types of triangles. Learn how to use the formula for area of triangle to calculate the area of the triangle shown in the example in the video.

Volume of Cube - 7th Grade Math

In this video, You will learn how to find the Volume of Cube.
Cube Definition:
A cube is three dimensional shape which has all the sides such as length, height and width same in measurement.

To find the Volume of a cube, follow the formula which is L x W x H.
L stands for length.
W stands for width.
H stands for height.
In a cube all of the sides are of the same measurement and so we will multiply the same measurement three times.

Area of Parallelogram -7th Grade Math

Topic:Learn how to find the Area of Parallelogram

Parallelogram Definition:
Parallelogram is a flat shape with opposite sides parallel and equal in length.

To find the Area of Parallelogram, we have to multiple Base with Height, so our Formula will be

Area of Parallelogram= Base X Height
A=BXH

Area of Trapezoids -7th Grade Math

Learn How to Find the Area of Trapezoid.

Definition of Trapezoid:
Trapezoid is a four sided flat shape with straight sides that has a pair of opposite sides parallel

To find the area of Trapezoid, we have to add the two bases and then divide by 2 and then Multiply with Height of Trapezoid.

Formula for Area of Trapezoid =((Base1+ Base2)/2) X Height
