About this worksheet

What students practice

Students use volume formulas for cylinders, cones, and spheres.
Students find missing dimensions and combine volumes of solids.
Students use sample volumes to compare and predict tide-pool organism counts.

How to use

Use after introducing the three volume formulas. Have students show calculations on separate paper, then discuss why sample volume matters when comparing organism counts.

Tide-Pool Survey: Volumes Behind the Counts

Use cylinders, cones, and spheres to interpret field-trip measurements.

1. Measure the Survey Equipment

A marine biology class is counting tide-pool species on a field trip. Treat the equipment as ideal geometric solids. Keep π exact. When a blank follows “Volume =,” enter only the coefficient of π.

A cylindrical water-sample chamber has an inside diameter of 6 cm and an inside height of 4 cm. Which expression gives its volume in cubic centimeters?
