How many cubes with edge length 1/5
in fit in a 2 2/5 x 3 1/5 x 2 prism

96

Step-by-step explanation:

Given:

Length of edge of cube = 1/5

Measurement of prism =  2 2/5 x 3 1/5 x 2

                                      =

Question asked :

How many cubes with edge length 1/5  fit in a prism ?

Solution:

Surface area of a cube =

                                        =

                                        =

Volume of prism = Lenghbreadthheight

                           =  

                           =

Number of cubes fit in this prism = Volume of prism divided by Surface area of a cube

                                                    =    

                                                    =

               By cancelling 25 by 25 =   pieces of cubes

Thus,  96 pieces of cubes with edge length 1/5  fit in a 2 2/5 x 3 1/5 x 2 prism.

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
