Because since the formula is
V=1/3(Base Area) x h
V= 1/3 24 x h
1/3 of 24 is 8
V= 8 x h
Then height is 20cm
V = 8 x 20
V = 160

Charlotte has a large container of only red beads.
Harry has a large container of only blue beads.
Charlotte and Harry swap 40 beads.
This means that Charlotte gets 40 of Harry's blue beads in her container and Harry gets 40 of Charlotte's red beads in his container.
Charlotte now randomly picks 90 beads from her container and notices that 9 are blue.
Harry now randomly picks 80 beads from his container and notices that 70 are blue.
If all the beads were placed in one container, work out an estimate for the ratio of red to blue beads.
Simplify your answer fully.
Answers
Using it's concept, it is fond that the estimate for the ratio of red to blue beads is of 91:79.
What is the ratio between two amounts?The ratio between two amounts a and b is given by a divided by b, that is:
[tex]\frac{a}{b} = a:b[/tex]
In this problem, considering Charlotte's and Harry's beads, there are 81 + 10 = 91 red beads and 9 + 70 = 79 blue beads, hence the ratio is given by:
91:79.

The length of a rectangle is 5m longer than the width. The perimeter of the rectangle is 82m. Find the length and width of the rectangle.
Answers
Answer:
length: 23 mwidth: 18 mStep-by-step explanation:
The given dimensions are related by the perimeter formula for a rectangle.
Let w represent the width in meters. Then (w+5) represents the length. These values can be put into the perimeter formula, which can be solved to find w.
P = 2(L +W)
82 = 2((w+5) +w) . . . . fill in for L and W
41 = 2w +5 . . . . . . . . divide by 2
36 = 2w . . . . . . . . . subtract 5
18 = w . . . . . . . . . divide by 2. This is the width.
w+5 = 18+5 = 23 . . . . find the length
The length of the rectangle is 23 m; the width is 18 m.

I don't understand this
the box is in the shape of a cuboid.
height: 60cm
length: 100cm
width: 40cm
Joh wants to fill the box with grit.
A bag of grit costs £2.50
there are 8000cm^3 of grit in a bag.
Joh has £70 to spend on the grit.
Does John have enough money to buy all the grit he needs to fill the box completely?
Answers
We calculate the volume of the cuboid :
60 x 100 x 40 = 240000 cm^3
If every bag has 8000 cm^3 of grit, he will need 240000 : 8000 = 30 bags
Every bag cost £2.50, so he will need £2.50 x 30 = £75
Since he only has £70, he doesn't have enough money to buy the grit.
