Answer:
Volume of the solid figure = 1131 cubic inches
Step-by-step explanation:
Volume of solid figure = Volume of half cylindrical prism + Volume of the rectangular prism
Volume of half cylindrical prism =
=
= 339.29 cubic inch.
Volume of the rectangular prism = (length × width × height)
= 11 × 6 × 12
= 792 cubic inches
Volume of the solid figure = 339.29 + 792
= 1131.29
≈ 1131 cubic inches
Let the number of girls be g.
Let the number of boys be b.
Now we can write these equations;
3g + 4b = 92 ..........(1)
g + b = 26 ...............(2)
b = 26 - g ................(3)
Plugging the expression for b in (3) into (1), we get:
3g + 104 - 4g = 92 ......(4)
Solving (4) we get
g = 12
So the number of girls in the class is 12.
