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

How do you find the length of a rectangular prism?

You can compute this only if you know the volume and height, or volume and cross-sectional area. The volume of a rectangular prism is Length X Width X Height. The volume is therefore Length X Area (cross-section). L = V/A L = V/(WH)


What is the volume of the rectangular prism with length l width w and height h?

The volume of a rectangular prism is given by the formula volume of rectangular prism = length x width x height If the length is l, the width is w and the height is h the volume is given by volume = lwh

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.

How do you measure rectangular prisms?

To measure a rectangular prism, you need to determine its three dimensions: length, width, and height. These measurements are typically taken using a ruler or measuring tape. The volume of the prism can then be calculated by multiplying these dimensions together (Volume = length × width × height). Additionally, the surface area can be calculated using the formula Surface Area = 2(length × width + length × height + width × height).
