Q13 A gardener needs to buy compost to fill this tub.

REY [17]

Answer:

5 bags

Step-by-step explanation:

The volume of the tub is the product of its dimensions:

V = (1.8 m)(0.5 m)(0.25 m) = 0.225 m³

There are 1000 L in 1 m³, so this volume in liters is ...

(0.225 m³)(1000 L/m³) = 225 L

At 50 L per bag, the gardener needs ...

(225 L)/(50 L/bag) = 4.5 bags

The gardener probably cannot purchase a partial bag, so must buy more than is needed.

The gardener must buy 5 bags of compost to fill the tub.
