Answer: 120m
Step-by-step explanation:
Let the height of the building be represented by x.
Since the height of a tower is 15m more than tiwce the height of a building, the height of the tower will be:
= (2 × x) + 15
= 2x + 15
Since the tower is 255m tall, therefore,
2x + 15 = 255
2x = 255 - 15
2x = 240
x = 240/2
x = 120
The height of the building is 120m
Answer:
Step-by-step explanation:
When you find the volume of prisms, you're essentially taking the area of the base and multiply it by the length, in varied orientations.
In this case, I'd start by finding the area of the parallelogram facing us.
The formula for a parallelogram's area is the same as a rectangle's:
A = b x h
In this case, h = 3 cm and b = 8 cm.
A = 24 cm²
Now, you multiple the area by the length of the parallelogram, which is 8 cm.
V = 24 cm² x 8 cm
= 192 cm³
