A = 2lw + 2lh + 2wh
so A - 2lw = 2lh + 2wh = 2h(l+w) = h*2(l+w)
so h = 1/2*(A-2lw)/(l+w)

Formula for surface area of rectangular prisms?
2lw + 2lh + 2wh
Surface area of rectangular prism?
surface area of a rectangular prism is the formula: 2lw+2wh+2lh
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 surface area of a rectangular prism that is 6 inches long 8 inches wide and 2 inches high?
To find the total surface area of a prism you add the lateral area and the areas of the two congruent bases. The formula is:Surface area = L.A. + 2B, where B is the area of the base.S.A. = L.A. + 2BSince the L.A. = 2(lh + hw) added to the area of the two bases, 2B = 2lw, another formula for the surface area can be S.A. =2(lh + hw + lw).By substituting the given values, l = 6 in, h = 2 in, and w = 8 in, in the surface area formula we have:S.A. = 2(lh + hw + lw)S.A. = 2[(6)(2) + (2)(8) + (6)(8)] = 2(12 + 16 + 48) = 2(76)S.A. = 152Thus, the surface area of the prism is 152 square inches.
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.
