Volume is the measurement of the amount a 3D object can hold. Each 3D object has 3 measurements: length, width, and height.. This object is a rectangular prism. Its volume is found as V = l*w*h. Substitute h = 3.75, l = 8.5, and w = 4.5. Then simplify for the volume.
The probability that a random variable is greater than or equal to z standard deviations from the mean in a standard normal distribution he P(z≤a)+P(z>a)=1, so P(z>a)=1-P(z≤a)=1-.7116=.2884
