A, use the Pythagorean theorem. A squared plus B squared equals C Squared, or A+B=C. In other words, 24 (Which is C) - 8 (Which is B)=16 (Which is A).
Answer:
a) 300
b) 900
Step-by-step explanation:
The length of the rectangle is 5 and the width is 3...
But since the rectangles are connected together, we could just work the problem like this:
5 x 2 = 10
_____________
3 x 5 = 15
15 x 2 = 30
The surface area of the shape is 10 x 30 = 300
______________________________________________
If the dimensions of the box were tripple, we would need to multiply the surface area by 3:
300 x 3 = 900
For the second question, the answer would be 900
Hope this helped you :-)
