If the standard volume of a cube is 1.5cm³ calculate the
cm
percentage error in measuring its
volume which is found to be 1.6cm³

A:6.7%
B:-6.7%
C:5%
D:-5%
E:4%

6.7 %

which agrees with answer A in your list.

Step-by-step explanation:

If the standard volume is 1.5 cubic cm, and the measured volume is 1.6 cubic cm, then the difference between these two is :

1.6 - 1.5 = 0.1 cubic cm. and therefore the percentage error is given by:

0.1/1.5 = 0.066666...which corresponds to a rounding of 6.7%

Recall as well that percent error is always expressed as a positive number.

a - base

b - exponent

so,
