Imagine a 10 kg chunk of aluminum (density = 2.7 g/cm3) and a 10 g chunk of iron (density = 7.9 g/cm3). which of the following is true? a. the chunk of iron is more massive than the chunk of aluminum. b. the chunk of aluminum's volume is smaller than the chunk of iron's volume. c. the chunk of iron's volume is smaller than the chunk of aluminum's volume. d. both objects have the same volume.

 C. The chunk of iron's volume is smaller than the chunk of aluminum's volume.

Step-by-step explanation:

Given: The mass of aluminum chunk = 10 kg

In grams , the mass of aluminum chunk = 1000 g   [∵ 1 kg = 1000 g]

The mass of iron chunk =10 g

i.e The chunk of aluminum is more massive than the chunk of iron.

Density of Aluminum chunk =

Density of iron chunk =

The formula of volume is given by :-

Clearly, The chunk of iron's volume is smaller than the chunk of aluminum's volume.

answer: options?

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
