Volume =length *breadth *height
Volume =area of the cross section *height
320=area of the cross section * 8
Area of the cross section =320/8
=40cm2
The volume of the cube that perfectly fits an 18 ft³ pyramid is calculated as (C) 54 ft³.

What is a cube?</h3>
- A cube is a three-dimensional solid object with six square faces, facets, or sides, three of which meet at each vertex.
- The cube is one of the five Platonic solids and the only regular hexahedron.
- It has six faces, twelve edges, and eight vertices.
To find the volume of the cube that perfectly fits an 18 ft³ pyramid:
We have been provided that:
- 18 cubic feet is the volume of the pyramid.
- Now, in order for this pyramid to fit exactly into a cube, the base of the pyramid must be square, and the height of the pyramid must be equal to the height of the cube.
- We can conclude from this that the volume of a cube equals three times the volume of a pyramid.
- So, the volume of the cube = 3 × 18
- The volume of Cube = 54 ft³
Therefore, the volume of the cube that perfectly fits an 18 ft³ pyramid is calculated as (C) 54 ft³.

(D) 72 cubic feet
Answer:
B
Step-by-step explanation:
A. (1.5)2 = 3 which is rational.
B. Root of 41 cannot be expressed as a fraction of p/q, where p and q are integers and q not equal to 0.
C. Root of 49 = 7 which is rational.
D. 15(2) = 30 which is rational
Answer:
is that lil huddy in your pfp lol (melanin king)
Step-by-step explanation:
The answer is 28.
Check: 28-12= 16
1/4 of 16= 4
3/4 of 16= 12
so Carmen takes 3/4 more time of the trip to the market when she return s home.
