L = 2 W
B = L x W = 2 W²
Side Area = 2 W H + 2 L H = 2 H ( W + L ) = 6 H W
V = 2 W² H = 10
H = 5 / W²
Cost = 15 * 2 W² + 9 * 5/W
= 30 W² + 270/ W 
C ` = 60 W - 270 / W² 
= ( 60 W² - 270 ) / W² = 0
60 W² = 270
W ² = 270 : 60
W² = 4.5
W = √ 4.5 = 2.12
Cost (min) = 15 * 2 * 4.5 + 30 / 2.12 = 135 + 14.15 = $149.15
Answer: The cost of materials for the cheapest such container is $149.15.

How many cubes are needed to fill in the rectangular prism?
tatyana61 [14]

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 = 3\frac{1}{4}=\frac{13}{4} in

Volume of the prism = length × width × height

                                 $=20\times2\times\frac{13}{4}

                                 = 130 in³

Volume of the prism = 130 in³

Length of the cube = \frac{1}{4} in

Volume of the cube = length × length × length

                                 $=\frac{1}{4} \times\frac{1}{4} \times\frac{1}{4}

                                 $=\frac{1}{64} \ \text{in}^3

Volume of the cube = 0.015625 in³

$\text{Number of cubes}=\frac{\text{Volume of the prism}}{\text{Volume of cube}}      

                            $=\frac{130}{0.015625}

                            = 8320

Number of cubes = 8320

Hence 8320 cubes can fit into the prism.
