Hello!
To find the volume of a rectangular prism you do hwl
h is height
w is width
l is length
4.2 * 5.3 * 12.1 = 269.346
The answer is 269.3 cubic centimeters
Hope this helps!
We are given
△ABC, m∠A=60° m∠C=45°, AB=8
Firstly, we will find all angles and sides
Calculation of angle B:
we know that sum of all angles is 180
m∠A+ m∠B+m∠C=180
we can plug values
60°+ m∠B+45°=180
m∠B=75°
Calculation of BC:
we can use law of sines

now, we can plug values



Calculation of AC:

now, we can plug values



Perimeter:

we can plug values


Area:
we can use formula

now, we can plug values
