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
I think the answer is 1/3 because you can simplify 4/12 into 2/6 and that can also be simplify into 1/3. Sorry if I am wrong let me know if i'm right
Answer:
Step-by-step explanation:
Im assuming that the cost of the house isn't per day, so it would be 6 days. I just added 60 to 1180 and counted how many times i added it. To check my work, you can just subtract 1180 from 1540, then divide by 60.
Sorry if this is wrong, but i tried my best. If its correct do you mind making me brainliest lol
Answer:
2198 cm²
Step-by-step explanation:
Total surface area of a cylinder = 2πrh + 2πr²
Radius, r = diameter/2
= 20cm/2
= 10 cm
Height, h = 25 cm
Total surface area of a cylinder = 2πrh + 2πr²
= 2*3.14*10*25 + 2*3.14*10²
= 1,570 + 6.28*100
= 1,570 + 628
= 2198 cm²
Total surface area of a cylinder = 2,198 cm²
