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!
What are 2 formulas to find the area of rectangle?
A= 2lw+2lh+2wh
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)
What is the formula for surface area of a rectangular solid?
You have to visualize the 3-D object. Think in your mind that this object has six sides. To find the surface area you need to add all of the areas of these sides together. In order to do that you need this formula... S.A. = 2(L*H) + 2(L*W) + 2(H*W) L=length H=height W=width Go to the related link below for a good representation

A equals 2lw plus 2lh plus 2wh solve for h?
A = 2lw + 2lh + 2wh so A - 2lw = 2lh + 2wh = 2h(l+w) = h*2(l+w) so h = 1/2*(A-2lw)/(l+w)

What is the formula for the surface area of a rectangular prism?
1/3 bh x h divided by 2 It depends on the dimensios of the cuboid (rectangular prism). If it has edge lengths a,b and c then it is made of three pairs of rectangles of area ab, ac and bc. So suface area = 2(ab + bc + ca)
