A rectangular prism has a base that measures 5 centimeters by 3 centimeters and a height of 1/2 centimeters. Cameron fills the prism with image centimeter cubes. Which of the following statements is TRUE? a) the rectangular prism will have a perimeter of 32 centimeters along the base
b) cameron will use a total of 120 coins to fill the rectangular prism
c) there will be 2 layers of cubes in the prism
d) cameron will use 60 cubes on the bottom layer

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
