Find the volume 12 points
1 answer:
<em /><u>The volume of the smaller cube:
</u>Volume of a cube = Length³
<u></u>Volume of a cube = 1³ = <u>1 ft</u>.³
<u>The volume of the larger cuboid:
</u>Volume of a cuboid = Length × Width × Height
Volume of a cuboid = 13 × 7 × 8
= 728 ft.³
<u>The volume of the composed figure:
</u>728 ft³ + 1 ft.³ = 729 ft³
</u>Volume of a cube = Length³
<u></u>Volume of a cube = 1³ = <u>1 ft</u>.³
<u>The volume of the larger cuboid:
</u>Volume of a cuboid = Length × Width × Height
Volume of a cuboid = 13 × 7 × 8
= 728 ft.³
<u>The volume of the composed figure:
</u>728 ft³ + 1 ft.³ = 729 ft³

400 children and 600 adults bought tickets.
Step-by-step explanation:
Given,
Cost of one child ticket = $14
Cost of one adult ticket = $32
Total attendance = 1000
Revenue generated = $24800
Let,
x be the number of children.
y be the number of adults.
According to given statement;
x+y=1000 Eqn 1
14x+32y=24800 Eqn 2
Multiplying Eqn 1 by 14
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 18
Putting y=800 in Eqn 1
400 children and 600 adults bought tickets.
