  • I don't get how the "3" is there when ur talking about "cubed" HELP!!!

  • @xxtwilightfannxx

    The units are cubed because we're multiplying three dimensions. The width, the length, and the height each have a unit, like inches, for example.

    We usually don't think of it this way, but we could include the units in our multiplication, something like this:

    (2 in)(4 in)(6 in) = 48 in^3

    I hope that helps! :-)

  • My teacher asked me to find the surface area and volume of a rectangle on my quiz .

  • @n1a2t3a4s5h6a71

    Do you mean a rectangular prism?

    A rectangle is a two dimensional figure and would only have area and perimeter.

    To find the surface area of a rectangular prism, we need to find the areas of each of the rectangles that make up the surfaces of the object and add them all up.

  • i <3 u

  • @mbrandl11 Thanks so much!!!

  • @n1a2t3a4s5h6a71

    you just need to use the formula then substitute "D

    Surface Area = 2(L x w) + 2( W x H) + 2 (h x L)

    V = L x W x H

    where: L is length

    W is width

    H is height

  • i'll guess .. you are making this vid while your so sleepy !!
