The volume of prism A is 60 cubic units, and the volume of prism B is half the volume of prism A. What is the value of a?

Alexxx [7]

Answer:

a=3.91

Step-by-step explanation:

V=a^3

since volume of B is Half of A then : V of A = 2 volume of B

a^3=2a^3

a^3 for A=60

or ∛a = ∛60= 3.91

volume of B =1/2 A =30

Answer:

2 $\frac{1}{20}$

Step-by-step explanation:

for question a)

It would be easier if you converted these to improper fractions (currently it is in the form of a proper fraction)

to convert to improper fraction, you would multiply the denominator (bottom no. of fraction) by the whole number , then add that with the numerator (top no. of fraction) and put the whole thing over the denominator.

E.g.

7 $\frac{1}{4}$ = 7x4 + 1 = 29

Thus, improper fraction would be $\frac{29}{4}$

do same thing for other one

thus , $\frac{26}{5}$

now,

$\frac{29}{4}$ - $\frac{26}{5}$

however, you can't do this as the denominators are not the same, so multiply them by a number which would give the a common denominator (20 would be the best option for common denominator)

$\frac{145}{20} -\frac{104}{20}$ = $\frac{41}{20}$
