1 Let its height be 5x and its width be 3x
2 So: 5x*3x*21 = 2835 => 315x2 = 2835 cubic cm
3 Divide both sides by 315 and then square root both sides
4 Then: x = 3 so then height is 5*3 = 15 cm and width is 3*3 = 9cm
5 Surface area: (2*15*9)+(2*15*21)+(2*9*21) = 1278 square cm
6 Check: 15*9*21 = 2835 cubic cm

What is the volume of a rectangular prism if the surface area is 34?
To find the volume of a rectangular prism when given the surface area, we need more information than just the surface area. The surface area of a rectangular prism is calculated using the formula 2lw + 2lh + 2wh, where l, w, and h are the length, width, and height of the prism, respectively. Without knowing at least one of these dimensions, we cannot determine the volume of the prism.
