Answer:

1024 in³

Step-by-step explanation:

Volume = (24 - 2x)(24 - 2x)(x)

= 576x - 96x² + 4x³

dV/dx = 576 - 192x + 12x² = 0

x² - 16x + 48 = 0

x² - 12x - 4x + 48 = 0

x(x - 12) - 4(x - 12) = 0

(x - 12)(x - 4) = 0

x = 4, x = 12

x can not be 12,

Because 24 - 2(12) = 0

So x = 4

Volume = (24 - 8)(24 - 8)(4)

= 1024

You need to subtract the two cutouts on each side, so the side of the box would be 24- 2x. X would then become the height of the box once folded.

The volume is found by multiplying the 4 dimensions:

The volume becomes x(24-2x)^2

Now take the derivative of the formula to solve for x

Dv/dx= (24-2x)^2 + x^2(24-2x)*-2

= 24-2x(24-2x-4x)=0

X =12 or 4

24-2x = 24-2(4) = 24-8=16

Volume = 16 x 16 x 4 = 1024 cubic inches.

Last year, 31 2 acres of strawberry fields produced approximately 14,700 pounds of strawberries. This year the number of acres p
USPshnik [31]

So in 5 acres of land produces 21,000 pounds of strawberries.

Step-by-step explanation:

Step 1:

Last year, 3\frac{1}{2} acres i.e 3.5 acres produced 14,700 pounds of strawberries. So we need to determine how many strawberries were produced per acre.

To do this we divide the total number of strawberries produced by the number of acres it was produced in.

The number of strawberries produced per acre= \frac{14,700}{3.5} = 4,200 pounds.

Step 2:

To determine the number of strawberries in 5 acres of land, we multiply the number of strawberries per acre by the number of acres.

The number of strawberries produced in 5 acres= 5(4,200) = 21,000 pounds.

So in 5 acres of land produces 21,000 pounds of strawberries.
