Answer:
- The area of the base of the pyramid, B, is 24 cm
- A rectangular prism with the dimensions of 9 cm by 4 cm by 6 cm will have 3 times volume of this pyramid.
Step-by-step explanation:
Volume of a rectangular based pyramid = 1/3{Base area × Height}
Base Area = Length × Breadth
Volume = 1/3{(Length × Breadth) × Height}
Given a rectangular pyramid with a height of 9 centimeters and a base with the dimensions of 4
centimeters by 6 centimeters
Base Area = 4cm × 6cm
Base area = 24cm²
If Height =9cm
Volume of the pyramid = 1/3 × 24 × 9
Volume = 24 × 3
Volume of the pyramid = 72cm³
If the shape is a prism, the volume will be base area × height
= 24 × 9
= 216cm³
It can be seen that volume of rectangular prism = 3 × volume of rectangular pyramid.
Answer:
Yes, it's enough information
Step-by-step explanation:
yes, there is enough information to determine the cost of 1 pack of pencils and 1 pack of pens
we just need an algebra of elimination and substition to find the coat of each. like this:
pencils = C
pen = N
2 C + 3 N = 8.25 (times by 2)
5 C + 2 N = 11.00 (times by 3)
------------------------- - (we eliminate the N)
4 C + 6 N = 16.50
15 C + 6 N = 33.00
------------------------- -
-11 C = - 16.5
C = (-16.5) : (-11) = $ 1.50
so the price of 1 pack of pencils is $ 1.50
now we use subtitution to find the price of 1 pack of pens
2 C + 3 N = 8.25
2 (1.50) + 3 N = 8.25
3.00 + 3 N = 8.25
3 N = 8.25 - 3.00
3 N = 5.25
N = 5.25 : 3 = $ 1.75
so the price of 1 pack of pencils is $ 1.75
