1) 7.5 miles north-east

2) 8 cubic inches

3) x = 6.24

Explanation:

1) Use pythagorus thereom:

a² + b² = c²

4.5² + 6² = c²

20.25 + 36 = c²

c = √56.25

c = 7.5

7.5 miles north-east

2) The ice is a cube,

Surface area = 24

Cube has 6 sides

24 / 6 = 4

1 side = 4

1 length = √4

1 length = 2

Volume = bhd

Volume = 2³

Volume = 8 in.³

3) ⅓x³ = 9

⅓x = (3√)9

⅓x = 2.08

x = 2.08 / ⅓

x = 6.24
