The answer is 1,342 cm squared. This problem is fairly simple, but ok.
y=28×9
=252
x=334-150
=184
h=254×100
=25400
Step-by-step explanation:
to check the equations substitute the values by the variables
Part A:
13²-5²=c
169-25=144
√144=12
Your height is 12.
Part B:
Base:
20(10)=200
Two triangular faces:
5(13)=65
65(2)=130
Rectangular faces:
20(13)=260
260(2)=520
200+130+520=850
They would need 850 cm of cardboard.
Hope this helps! Have an amazing day!
