How many cubes are needed to fill in the rectangular prism?

8320 cubes can fit into the prism.

Solution:

Convert mixed fraction into improper fraction.

Length of the prism = 20 in

Width of the prism = 2 in

Height of the prism = in

Volume of the prism = length × width × height

                                 = 130 in³

Volume of the prism = 130 in³

Length of the cube = in

Volume of the cube = length × length × length

Volume of the cube = 0.015625 in³

                            = 8320

Number of cubes = 8320

Hence 8320 cubes can fit into the prism.

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
