Formula for surface area of rectangular prisms?
2lw + 2lh + 2wh
Surface area of rectangular prism?
The surface area of a rectangular prism can be calculated by adding the areas of all six faces. The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l, w, and h represent the length, width, and height of the prism, respectively. This formula accounts for the two faces of each dimension (length, width, and height) on the rectangular prism.
What is the surface area of a rectangular prism with 3in x 4in x 8in?
Surface area of a rectangular prism is equal to 2LW+2LH+2HW. So for this object: 2*3*4+2*3*8+2*8*4=24+48+64=136 square inches.
Find the surface area of a rectangular prism that has the following dimensions length 2 ft width 14 in height 11 in?
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 is the total square area of 5m x 3m x 2m?
Sure thing, honey. To find the total square area of a 3D object, you gotta add up the areas of all its faces. So for a rectangular prism like this, you calculate 2lw + 2lh + 2wh, which gives you 46 square meters. Voilà, that's your answer, darling.
What surface area is equivalent when sa equals 2lw plus 2hw plus 2lh?
This would be the surface area of a rectangular prism or a cube.
What is the surface area of a rectangular prism with a length of 30cm a width of 40cm and a height of 2cm?
(2lw)(2lh)(2wh) multiply all of those together. i mean, plug in the numbers for the variables and solve. * * * * * Not quite. The correct answer is 2lw + 2lh + 2wh you add the three terms together!
How do you solve the surface area of a rectangle prism?
Area of a rectangular prism = 2lw + 2lh + 2wh, where l is length, w is width, and h is height.

What is an equation that can be used to find the height h of a rectangular prism with length 5cm width 3cm and surface area 62cm2?
The equation for the surface area of a rectangular prism is: A = 2lw + 2lh + 2wh Replace the variables you know, and solve for the remaining variable.
How do l work out the area of a rectangle?
Rectangular Solid Volume = Length X Width X Height V = lwh. Surface = 2lw + 2lh
How do you find the volume of a rectangular box with a surface area of 300 in2?
There is not enough information to solve this. You have 2 equations and 4 unknowns. Here are the equations: Area = 2LW + 2LH + 2HW = 300 ; Volume = L*W*H The unknowns are Length, Width, Height, and Volume.
