Answer:
Solution given;
l=4.5ft
b=2ft
h=2ft
now
volume=l*b*h=4.5*2*2=18ft³
is a required volume.
Now
total surface area =2(lb+lh+bh)
=2(4.5*2+4.5*2+2*2)=44ft²
is a total surface area.
Answer:
65 degrees
Step-by-step explanation:
A triangle has all three angles add up to 180 degrees.
34 + 81 + x = 180 degrees
115 + x = 180
x = 180 - 115
x = 65 degrees
Since both of the numbers have a variable which is x ready to be multiplied, there is no expression leading to the variable therefore you will add normally but you will need to put the missing variable which needs to be multiplied. So overall you can just add and once you get your variable you can be abe to multiply and get your final answer.
Hope this helps
