The volume (V) is given in terms of length (L), width (W), and height (H) by the formula ...
... V = LWH
Substituting your dimensions, you have
... V = (11.3 cm)·(18.9 cm)·(29 cm) = 6193.53 cm³ ≈ 6200 cm³
_____
The factor 29 cm has 2 significant digits, so that is the precision required of the answer. It could also be written with less ambiguity as to precision as 6.2 L. (Trailing zeros to the left of the decimal point are always ambiguous when it comes to significant digits.)
Answer:
143.26 sec
Step-by-step explanation:
Density = 4.3 g/l
Volume flow rate = 0.25 l/s
Mass flow rate = density x volume flow rate
= 4.3 x 0.25 = 1.075 g/s
This means 1.075 grams of the gas is released in 1 sec, therefore,
Time taken for leakage of 154 g of gas is
t = 154/1.075 = 143.26 sec
Speed=distance/time
average speed=(total distance)/(total time)
total distance=203+243=446
total time=3.5+4.5=8
average speed=(446)/(8)=55.75
