Can the numbers 24,32,40 be the lengths of three sides of a right triangle?
Naddika [18.5K]

Answer:

Yes

Step-by-step explanation:

using pythagorus theorum:   a^{2} + b^{2} = c^{2}

24^{2} +32^{2} =  1024+576

                        =   1600

40^{2} = 1600

thus, it can be concluded that these lengths can be the sides of a right-angled triangle.

Which is true about the volume or surface area of these prisms?
pshichka [43]
Your answer is the second option: The surface area of B is greater than the surface area of A.

To find the surface area, I found the area of the three sides shown and added them together, and then multiplied the answer by 2, so:

B:
8 × 2 = 16
8 × 10 = 80
10 × 2 = 20
+
= 116
116 × 2 = 232 cm²

A:
5 × 8 = 40
5 × 4 = 20
8 × 4 = 32
+
= 92
92 × 2 = 184 cm²

So therefore B > A because 232 > 184

I hope this helps!
