Answer:

£75 > £70 Therefore Sally is wrong.

Explanation:

1. First we need to find the volume of the sand pit

60x40x100= 24,000
$cm^{3\\$

Volume= 24,000
$cm^{3\\$

2. We need to convert 8 liters to
$cm^{3\\$ so, all the units are the same

1 liter= 1,000
$cm^{3\\$

8 liters= 8,000
$cm^{3\\$

3. We then do 24,000
$cm^{3\\$ divide by 8,000
$cm^{3\\$ to see how many bags, we need

24,000
$cm^{3\\$ / 8,000
$cm^{3\\$ = 30

so, Sally needs 30 bags

4. We know one bag cost £2.50 to know how much 30 bags cost we do

£2.50 x 30 = £75

so, we know 30 bags cost £75

5. Sally statement was said that it would cost less than £70 which is false as it costs £75

6. Therefore the final answer is £75>£70 so Sally is wrong.
