Answer:
As shown in picture,
volume of cone V = base area x height x (1/3) = pi x (4/2)^2 x 6 x (1/3) = 8 x pi
volume of cup V = base area x height = pi x (3/2)^2 x 3 = 6.75 x pi
(all the volumes are in cubic inches)
A - Incorrect
24 pack of cups: V = 24 x 6.75 x pi = 162 x pi
21 pack of cones: V = 21 x 8 x pi = 168 x pi
162 x pi < 168 x pi
B - Correct
12 pack of cups: V = 12 x 6.75 x pi = 254.5 > 250
C - Correct
14 pack of cones: V = 14 x 8 x pi =351.9 > 350
D - Correct
Volume of cylinder 8 tall, 6 wide: V = pi x (6/2)^2 x 8 = 72 x pi
12 pack of cups: V = 12 x 6.75 x pi = 80.4 x pi > 72 x pi
Hope this helps!

Answer:
m³
Step-by-step explanation:
The volume (V) of the cuboid is calculated as
V = lbh ( l is length, b is breadth and h is height ) , then
V = 1

Area of a rectangle is b•h so leaving off the two triangles, 4•3=12
Now area of a triangle is b•h/2 so (2•3)/2=3 then double that because there are two triangles, now 6, and add it to the area of the rectangle. 12+6=18
