A 6 by 2 feet rectangle
12 square feet.
17 and 22
134.6 feet
A rectangle is a 2-dimensional object, which will not have height. You want the volume for a cube with the length of 7 feet, width of 3 feet and height of 43 feet. The formula for the volume of a cube is Length X Width X Height = Area 7*3*43= 903 So the volume of a cube with those dimensions is 903 cubic feet.
The volume of that triangle is 49 feet
First of all a rectangle is a two dimensional shape. Its three dimensional counterpart is a cuboid. To find the volume we must multiply all of the dimensions: 48 * 25 * 17 = 20400 Then we have to put on the units at the end: 20400 ft^3
4 x 4 1 x 16
width is 5 feet
If the given dimensions are in feet then it is: 20*10 = 200 square feet
It could be a rectangle with dimensions of 6 feet by 3 feet.
