A gold bar is similar in shape to a rectangular prism. A gold bar is

7 1

approximately 7 in.x3 in.x1 in. If the value of gold is $1,214 per ounce,

about how much is one gold bar worth? Use the formula w 11.15n, where w

is the weight in ounces and n=volume in cubic inches, to find the weight in

ounces. Explain how you found your answer.

Answer 1

To find the weight of the gold bar in ounces, we can use the formula w = 11.15n, where w is the weight in ounces and n is the volume in cubic inches. The volume of the gold bar is given as approximately 7 in. x 3 in. x 1 in., which is 21 cubic inches. Substituting this value into the formula, we find that one gold bar is worth approximately 233.15 ounces.

Step-by-step explanation:

To find the weight in ounces, we can use the formula provided: w = 11.15n, where w is the weight in ounces and n is the volume in cubic inches.

In this case, the volume of the gold bar is given as approximately 7 in. x 3 in. x 1 in., which is 7 x 3 x 1 = 21 cubic inches.

Substituting this value into the formula, we have:

w = 11.15 x 21 = 233.15 ounces.

Therefore, one gold bar is worth approximately 233.15 ounces.

Answer 2

`Worth = \$284258.1`

Step-by-step explanation:

Given

`Dimension: 7in\ * 3in\ * 1in`

`Value = \$1214/oz` ---- value of Gold

Required

The worth of 1 gold bar

First, calculate the volume (n) of the gold bar

`n = 7in * 3in * 1in`

`n = 21in^3`

Next, calculate the weight of the gold bar using:

`w = 11.15n`

`w = 11.15 * 21`

`w = 234.15oz`

Multiply the value of Gold by the weight of the gold bar to get the worth of the gold bar.

`Worth =Value * w`

This gives:

`Worth = \$1214/oz * 234.15oz`

`Worth = \$1214 * 234.15`

`Worth = \$284258.1`
