Question

Which set of measurements will give you a volume of 168 cubic meters?

Answer 1

base = 3 cm, height of base = 4 cm, height of prism = 7 cm
base = 3 cm, height of base = 8 cm, height of prism = 7 cm
base = 6 cm, height of base = 4 cm, height of prism = 7 cm
base = 6 cm, height of base = 8 cm, height of prism = 7 cm

Answer 2

which 3 numbers multiply to 168

I know that the divisibility test for 3 is add the digits... if the answer is a multiply of 3 then 3 will be a factor

so 1 + 6 + 8 =15 so 3 is a factor

168/3 = 56

now find te factors of 56...

and then your answer will be

3, and the factors of 56

Answer 3

if 3 is a factor and the number is even then 6 is a factor

168/6 = 28

find the factors of 28

so the answer could be, 6, and the factors of 28
