Question 13
1 answer:
The difference, to the nearest gram, of the masses of the rectangular
prisms is 1393.2 grams.
<h3>What is the volume of the rectangular prism?</h3>The volume of the rectangular prism is the product of the length, breadth, and height of the given prism.
Volume of rectangular prism = (length x width x height)
Joe has a rectangular prism made of aluminum and a rectangular prism made of lead.
Each rectangular prism has a height of 6 cm, length of 9 cm, and width of 3 cm.
The volume of a rectangular prism made of aluminum = (length x width x height)
=
The volume of a rectangular prism made of lead= (length x width x height)
= 162 cubic cm
We know that mass = density x volume
The density of aluminum is approximately 2.70.
mass = 2.70 x 162
= 437.4 grams
The density of lead is approximately 11.3 cm3
mass = 11.3 x 162
= 1830.6 grams
The difference, to the nearest gram, of the masses of the rectangular
prisms 1830.6 - 437.4 = 1393.2 grams

The cost of each stone sphere is $ 36.81
<em><u>Solution:</u></em>
Given that,
An architect plans to buy 5 stone spheres and 3 stone cylinders
For the same amount, she can buy 2 stone spheres and 6 stone cylinders
Let "x" be that same amount
Let "a" be the cost of each stone sphere
Cost of each stone cylinder = $ 36.81
Therefore,
x = 5 stone spheres and 3 stone cylinders
x = 5a + 3(36.81)
Similarly,
x = 2 stone spheres and 6 stone cylinders
x = 2a + 6(36.81)
Equate both,
Thus cost of each stone sphere is $ 36.81
