A prism with a base area of 8 cm² and a height of 6 cm is dilated by a factor of 5/4 .
Andrei [34K]
The volume of the original prism is calculated by multiplying the area of the base by the height,
                               volume = (8 cm²)(6 cm) = 48 cm³
By the word dilated we mean to say that the dimensions of the new prism is 5/4 times that of the original solid. If we let x be the volume of the new solid,
                           x / 48 cm³ = (5/4)³
The value of x from the equation above is equal to 93.75 cm³.

If DE = 8, PS = 4, and PQ = 3, then what is the scale factor of DEFG to PQRS?
posledela

The scale factor of DEFG to PQRS is: 3/8.

<h3>What is a Scale Factor?</h3>
  • A scale factor of a dilation is the number by which the size of an original figure is changed to a new figure.
  • Scale factor is ratio of corresponding side of new figure to original figure.

Thus:

DE corresponds to PQ.

PQRS is the new figure.

DE = 8; PQ = 3

  • Therefore:

Scale factor of DEFG to PQRS = PQ/DE

Scale factor = 3/8.

Thus, the scale factor of DEFG to PQRS is: 3/8.
