Answer: 342 cm³
Step-by-step explanation: To find the volume of the rectangular prism, start with the formula for the volume or a prism.
Volume = length × width × height
Since we are not sure what the length, width, or height is in this problem, we can plug any of these numbers in for the length, width, or height. The commutative property of multiplication states that changing the order of the factors does not change the product.
Volume = (19 cm) (9 cm) (2 cm)
Volume = 342 cm³
Therefore, the volume of the rectangular prism is 342 cm³.

Answer:
Option D. No,they are not similar because their side lengths are not proportional.
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
In this problem If the rectangles are similar
then
The ratio of its corresponding lengths must be equal to the ratio of its corresponding heights
<u><em>Verify</em></u>

therefore
The rectangles are not similar because their side lengths are not proportional.
Answer:
If the geometric shape is classified as a quadrilateral and all angles are equal then each angle as a right angle measuring at 90 degrees.

Answer:
a(6)=2430
Step-by-step explanation:
a(1)=10
a(n)=3×a(n-1)
This is a geometric sequence, with ratio=3
a(2)=3×a(1)=3×10
a(3)=3×a(2)=3²×10
a(6)=3⁵×20=(27×9)×10=243×10=2430
