A pyramid is a 3-D structure with one base, whose outer faces are made of triangles, and meet at a single point at the top.
A prism is any 3-D shape with a base of any number of sides, another base with the same amount of sides, and faces joining the two together on every side of the bases.
12.
Shape A is a pyramid, because it has one base, and all the faces join together in at one point.
Shape B is a prism, because it has two bases, and faces joining every side of the bases.
Shape C is a prism.
Shape D is a pyramid.
For #13, you have to know the definition of a cube to figure out the math of how many cubes there are.
A cube is a 3-D shape with six sides, all made up of squares of the same size.
The box has a volume of 120 cubic inches, and each cube is 1 inch. Since every side of a cube is equal, a 1-inch cube is one cubic inch.
This means that a box with a volume of 120 cubic inches will fit 120 of the 1 inch cubes.
1 layer of the cubes, in the diagram, is 8 cubes by 3 cubes, or 24 cubes total.
To find the number of layers needed to fill the box, you divide 120 by 24.
120 ÷ 24 = 5
The answer to #13 is 5 layers.

Question:
1) The kick is good! The ball passes about 10 feet above the crossbar.
2) The kick is good! The ball clears the crossbar by approximately 14 feet.
3) The kick is good! The ball clears the crossbar by about 4 feet.
4) The kick is not successful. The ball is 2 feet too low.
Answer:
The correct option is;
3) The kick is good! The ball clears the crossbar by about 4 feet.
Step-by-step explanation:
Here we have
Horizontal distance from goal, x = 36 yards = 108 ft
Vertical distance of goal, y = 10 ft
Angle of elevation of ball = 34°
Initial velocity of ball, v₀ = 68 ft/s
∴ Vertical component of velocity = = v₀×sin(θ₀)×t - g×t
Horizontal component of velocity = vₓ = 68×cos(34) = 56.375 ft/s
The equation for projectile motion is as follows
x = x₀ + v₀×cos(θ₀)×t
y = y₀ + v₀×sin(θ₀)×t - 1/2×g×t²
Where:
x₀ = Initial horizontal displacement of the ball = 0
y₀ = Initial vertical displacement of the ball = 0
t = Time of flight of the ball
Therefore;
108 = 0 + 68×cos(34)×t which gives;
t = 108/56.375 = 1.916 seconds
Hence, y = y₀ + v₀×sin(θ₀)×t - 1/2×g×t² gives;
y = 0 + 68×sin(34)×1.916 - 1/2×32.2×1.916²
y = 72.85 - 59.09 = 13.76 ft, hence the vertical location of the ball at 36 yard is 13.76 ft where the crossbar is at 10 ft hence the ball clears the crossbar by 13.76 ft - 10 ft = 3.76 ft ≈ 4 ft
Therefore, the kick is good! The ball clears the crossbar by about 4 feet.
