Find the surface area of a rectangular prism that has the following dimensions length 2 ft width 14 in height 11 in?
FreshDominican34
Designating the prism's length by l, the prism's width by w, and the prism's height by h, the general formula is 2lw+2lh+2hw, because there are two surfaces that are rectangles with length and width of the prism's length and width, two surfaces that are rectangles with length and width that are the prism's length and height, and two surfaces that are rectangles with length and width that are the prism's width and height. To give all dimensions the same units, multiply the 2 foot width by 12 in/ft to yield 24 inches Applying the formula yields:
(2 X 24 X 14) + (2 X 24 X 11) + (2 X 11 X 14) = 1508 square inches.

What comes first width by height or height by width when defining rectangular duct dimensions?
width always comes first
What is the surface area of a right cone with a slant height of 6 and a radius of 9?
These dimensions are not possible for a right cone. The radius must be less than the slant height. If we reverse the dimensions (radius 6, slant height 9) the total surface area will be about 282.74 units2

How do you calculate surface-area-to-volume ratio of a rectangular solid?
The answer depends on what information you have been provided with. If you have only the linear dimensions then it is:2*(1/Length + 1/Breadth + 1/Height)

How do you calculate the area of a rectangular crystal surface?
It is 2*(Length*Breadth + Breadth*Height + Height*Length).
How do you find the height of a rectangular box given the width and length?
You cannot. There is no relationship between the height and the other two linear dimensions of a box.
How does the dimensions affect the area of a rectangular prism that is halved?
The dimensions are the length width and height of the prism. So if the prism is halfed then you would have to cut the dimensions in half depending on where the prism was cut.
Total surface area of rectangular solid?
The formula for the surface area of a rectangular solid is = 2lw + 2lh + 2wh 2(length x width)+2(length x height)+2(width x height)
