To solve the problem of determining the total mass of each object using the information provided in the image, we need to read the values from the three beams of the triple beam balance and sum them up. The triple beam balance consists of:
1.
The largest beam (typically measures hundreds of grams).
2.
The middle beam (typically measures tens of grams).
3.
The smallest beam (typically measures single grams and tenths of grams).
Step-by-Step Solution:
####
Problem 1:
-
Largest beam: The pointer is at
70 grams.
-
Middle beam: The pointer is at
50 grams.
-
Smallest beam: The pointer is at
4.6 grams.
Total mass = 70 grams + 50 grams + 4.6 grams =
124.6 grams
####
Problem 2:
-
Largest beam: The pointer is at
30 grams.
-
Middle beam: The pointer is at
100 grams.
-
Smallest beam: The pointer is at
3.4 grams.
Total mass = 30 grams + 100 grams + 3.4 grams =
133.4 grams
####
Problem 3:
-
Largest beam: The pointer is at
60 grams.
-
Middle beam: The pointer is at
400 grams.
-
Smallest beam: The pointer is at
7.8 grams.
Total mass = 60 grams + 400 grams + 7.8 grams =
467.8 grams
Final Answers:
1. The mass is
124.6 grams
2. The mass is
133.4 grams
3. The mass is
467.8 grams
Boxed Final Answers:
\[
\boxed{124.6 \text{ grams}, 133.4 \text{ grams}, 467.8 \text{ grams}}
\]
