Describe how volume is measured. Explain why linear or square units cannot be used. Question content area bottom Part 1 Choose the correct answer below. A. In order to measure volume a square unit is used. A square unit is a square with each side being one unit in length. The volume is found by counting the number of square units contained within the region. Linear and square units cannot be used because they measure distances of straight lines. B. In order to measure volume a cubic unit is used. A cubic unit is a cube with each side being one unit in length. The volume is found by counting the number of cubic units contained within the region. Linear units cannot be used because they measure distances of straight lines, and square units cannot be used because they measure square areas. C. In order to measure volume, length, width, and height are added together. The volume is found by counting the number of cubic units contained within the region. Linear units cannot be used because they measure distances of straight lines, and square units cannot be used because they measure square areas
