2 answers:
Answer: The correct option is (B) 6 m².
Step-by-step explanation: We are given to select the correct option that could be the area of the face of the rectangular prism in the figure.
From the figure, we note that
the dimensions of the faces of the rectangular prism and the corresponding areas are as follows:
(A) 2m × 3m.
The area of this face will be
(B) 2m × 4m.
The area of this face will be
(C) 3m × 4m.
The area of this face will be
So, the possible areas of the faces are 6 m², 8 m² or 12 m².
Thus, the correct option is (B) 6 m².

Answer:-1)The three sets of approximation of time will be
Time taken to fall tennis ball from height of 60 m =35.41014 s ≈35.410 s (to the nearest thousandth)
≈35.41s (to the nearest hundredth)
≈35.5 seconds(to the nearest tenth)
2)Time by the ball to hit the ground =35.5 seconds
Step-by-step explanation:
Time taken to fall tennis ball from height of 60 feet = 0.25 √60 s
So,time taken to fall tennis ball from height of 1 foot =0.25√60 divided by 60=
We know that 1 m = 0.3048 foot
⇒60 m =60×0.3048=18.288 feet
therefore, Time taken to fall tennis ball from height of 60 m = 18.288 ×time taken to fall tennis ball from height of 1 foot=
∴Time taken to fall tennis ball from height of 60 m =35.41014 s ≈35.410 s (to the nearest thousandth)
≈35.41s (to the nearest hundredth)
≈35.5 seconds(to the nearest tenth)
