Answer:

1233.68 g

Step-by-step explanation:

Given:

The weights are

1.21 kg

546 mg

23.14 g

Here,

the units of all the weights given are not uniform, also the options are provided in grams

Therefore, we will first convert all the weights in the uniform unit i.e in grams

thus,

we have

1.21 kg = 1210 g

546 mg = 0.546 g

23.14 g

hence,

the total mass = 1210 g + 0.546 g + 23.14 g = 1233.686 ≈ 1233.68 g

Hence, the correct answer is option 4. 1233.68 g

The United States five-dollar bill are 155.956 mm long and 66.294 wide. A stack of these bills fits inside a 156 x 66.3 x 66.3 m
maxonik [38]

Answer:

A) $5 × 25 = $75

B) 37.69%

Step-by-step explanation:

The dimension of five dollar bill:

Length = 155.956mm

Width = 66.294

Volume of box being occupied by 5 dollar bill = 258,473.68mm^3

Dimension of box :

156 x 66.3 x 66.3 mm

If volume of the 5—dollar bill is 258,473.68mm^3

Then, the Thickness of the five dollar stack equals :

Volume = Length × width × height

258,473.68mm^3 = 155.956mm × 66.294 × height

258,473.68 = 10338.947064 × h

h = (258473.68/10338.947064)

h = 25.000000003288 = 25

Therefore, the amount of money in the box is:

$5 × 25 = $75

Percentage of box volume taken up by $5 bill

Volume of the box:

156 x 66.3 x 66.3 mm = 685727.6399mm^3

Volume of box being occupied by 5 dollar bill = 258,473.68mm^3

(258,473.68 / 685727.6399) × 100

=37.69%
