Answer:

Step-by-step explanation:
Use the acronym SOH-CAH-TOA
sin = 
So opposite is 3 and hypotenuse is 4.
tan = 
So opposite is -3 and adjacent is 4.
cos = adjacent/hypotenuse
cos = 
20 - (3 x 2 cubed - 5 ) The Answer Is 1
Answer: 4,320 inches cubed.
Step-by-step explanation:
step 1----- Volume of 1 canvas box
Volume of solid for a rectangular box = Length x width xHeight
where Length= 12inches,
Width= 10 inches
Height= 12 inches
Volume of a Canvas box= 12 X 10 X 12= 1440 inches cubed
Step 2== Volume of 3 canvas boxes
1 canvas box = 1440 inches cubed
therefore 3 canvas boxes =
1440 x 3= 4320 inches cubed.
