7+8=x/3<br> how do i solve this
Archy [21]

Because this is addition, you must reverse the process by (maybe) doing x/3 and 8/1 or 7/1. Cross multiply the numerators and denominators.

Find the total surface area of the rectangular prism in square millimeters. 2cm 6 cm 9cm
Ket [755]
<h3>Answer:  168 square cm</h3>

==============================================

Work Shown:

  • L = 2 = length
  • W = 6 = width
  • H = 9 = height

The order of length, width and height doesn't matter

SA = surface area of rectangular prism

SA = 2*(LW + LH + WH)

SA = 2*(2*6 + 2*9 + 6*9)

SA = 2*(12 + 18 + 54)

SA = 2*(30+54)

SA = 2*(84)

SA = 168 square cm

How can I convert measurements of weight? Give an example <br> ( please help)
sashaice [31]

Measurements of weight can be converted quite easily! However, you may need some extra information if you are converting from things like pounds to kilograms.

For conversions like pounds to kilograms, you will need a conversion factor. Most of the time, a quick Google search will find you this factor. For example with pounds and kilograms, 2.205 pounds is equal to 1 kilogram. To find the number of kilograms in a pound, you would divide the number of pounds by 2.205. To find the number of pounds in a kilogram, you would multiply the number of kilograms by 2.205.

For other conversions, like kilograms to grams, you would need to remember your prefixes. For example, kilo means 1000. Grams is the single unit, so that means 1000 grams is equal to 1 kilogram. To find the number of grams in a kilogram, you would multiply the number of kilograms by 1000. To find the number of kilograms in a number of grams, you would divide the number of grams by 1000.

Hope this helps!! :)
