Answer: 3.84 m
Step-by-step explanation: The biggest clue here is that the scale factor is 1:12.
1:12=32:
To find , multiply 32 by 12. 32x12 is 384. You can't say the answer is 384, however, since the label for the actual water tower says "m" for meters instead of "cm" like for the model. 384 cm is equal to 3.84 m.
Hope this helped! ;)
The cuboid on the left has a volume of
.. (11 yd)*(5 yd)*(2 yd) = 110 yd^3
The cuboid at upper left has a volume of
.. (10 yd)*(4 yd)*(2 yd) = 80 yd^3
The total volume is (110 +80) yd^3 = 190 yd^3.
