Answer:
Option C) 4 cubic inches is the volume of the rectangular prism.
Step-by-step explanation:
It is given that, 108 cubes with an edge length of 1/3 inch are needed to fill a rectangular prism.
Therefore, the volume of the rectangular prism is equal to the volume of the 108 cubes needed to fill that rectangular prism.
So, we need to find out the volume of those 108 cubes in order to find the volume of the rectangular prism.
The formula for finding the volume of a cube is given by,
Volume of a cube = a³
where a represents the edge length
We know that, the edge length is 1/3 inch.
⇒ a = 1/3
Volume of a cube = (1/3)³
⇒ 1/3 × 1/3 × 1/3
⇒ 1/27 cubic inches
To find the volume of 108 cubes :
⇒ 108 × volume of one cube
⇒ 108 × 1/27
⇒ 4 cubic inches.
∴ The volume of 108 cubes is the volume of rectangular prism which is 4 cubic inches (option C)
Answer:
1.52
Step-by-step explanation:
We're rounding to the nearest hundredth.
According to the rules of rounding, we need to look 1 digit place to the right. If that digit is 
5, then we round up. Otherwise, we round down.
For 1.518, we need to look at 8 (since we're rounding to the hundredth).
, so we round the hundredths digit up.
So 1.518 rounds up to 1.52
Given:
A diagram of Aram's observations.
To find:
The measure of the missing angle.
Solution:
From the given figure it is clear that the three angles 
lie on a single point and right side of a straight line.
So, the sum of angle must be 
.
Therefore, the measure of the missing angle is .
Answer:
504 millimeters (or 50.4 cm)
Step-by-step explanation:
- Width of key in student calculator = 14 millimeter (1.4 cm)
- Width of key in demonstration calculator = 2.8 cm
<u><em>Thus, the demonstration calculator's dimensions are </em></u><u><em>twice</em></u><u><em> that of students' (in cm)</em></u>
<u><em /></u>
Also given, student calculator height as 252 millimeters (25.2 cm)
Thus demonstration calculator height will be twice of that = 50.4 cm (or 504 millimeters)
