Solve and answer the following prism

1st) Surface Area = 178.7 cm²

Volume = 105 cm³

2nd) Surface Area = 51 m²

Volume = 15 m³

Step-by-step explanation:

1st) 1/2x2.5x7=8.75 (2 of these - one on each end)

7x12=42

12x2.5=30

12x7.433=89.20

S.A=8.75+8.75+42+30+89.2=178.7

Volume=8.75x12=105

2nd) 1/2x3x2=3 (two of these - one on each end)

5x4=20

5x3=15

5x2=10

S.A.=3+3+20+15+10=51

Volume = 3x5=15

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
