What is the total surface area of a right rectangular prism with the base of 2 cm by 3 cm and a heightof 6 cm

72

Step-by-step explanation:

We can use the equation A=2(wl+hl+hw)  to calculate surface area. All we have to do is substitute the known values.

A=2(3(2)+6(2)+6(3)

Now, simplify.

A=2(6+12+18)

A=2(36)

A=72

The total surface area is 72.

Hope this helps!

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
