Answer:
The new volume is 14,850cm³
Step-by-step explanation:
Given
Volume of a rectangular prism = 550cm
Required
Value of volume when the dimensions are tripled.
The volume of a rectangular prism is calculated using the following formula.
V = lbh
<em>When Volume = 550, the formula is written as follows</em>
550 = lbh
<em>Rearrange</em>
lbh = 550
However, when each dimension is tripled.
This means that,
new length = 3 * old length
new breadth = 3 * old breadth
new height = 3 * old height
<em>Let L, B and H represent the new length, new breadth and new height respectively</em>
In other words,
L = 3l
B = 3b
H = 3h
Calculating new volume
New volume = LBH
Substitute, 3l for L, 3b for B and 3h for H;
V = 3l * 3b * 3h
V = 3 * l * 3 * b * 3 * h
V = 3 * 3 * 3 * l*b*h
V = 27 * lbh
Recall that lbh = 550
So,
V = 27 * 550
V = 14,850
Hence, the new volume is 14,850cm³
Answer:
42+30=72
7+5=12
72-12=60
Blank=60
Step-by-step explanation:
The answer is Y=5/3 or 1.6
Answer with Step-by-step explanation:
We are given that height of projectile after t seconds is given by
a.h(t)=144 ft
t-3=0
t=3
After 3 s, the height of the project will be 144 feet in the air.
b.h(t)=0
At t=0, the initial position of projectile
At t=6 s , the projectile will hit the ground.
It would be -5. assuming that back is negative and forward is positive, Kyle has moved a total of 5 spaces back
