Answer: 4,320 inches cubed.

Step-by-step explanation:

step 1----- Volume of 1 canvas box

Volume of solid for a rectangular box = Length x width xHeight

where Length= 12inches,

Width= 10 inches

Height= 12 inches

Volume of a Canvas box= 12 X 10 X 12= 1440 inches cubed

Step 2== Volume of 3 canvas boxes

1 canvas box = 1440 inches cubed

Nimfa-mama [501]

Answer:

d. about 50 times larger

Step-by-step explanation:

The given expressions for magnitude (M) can be solved for the intensity (I). Then the ratio of intensities is ...

$\dfrac{I_2}{I_1}=\dfrac{I_0\cdot 10^{M_2}}{I_0\cdot 10^{M_1}}=10^{M_2-M_1}=10^{4.2-2.5}\\\\=10^{1.7}\approx 50$

The larger earthquake had about 50 times the intensity of the smaller one.
