Find the volume 9m by 5m by 9m

405m³

Step-by-step explanation:

I will assume these are the dimensions of a square or rectangle. To find the volume, we can use the formula [ v = b * h * l ].

v = 9 * 5 * 9

v = 45 * 9

v = 405m³

Best of Luck!

Step-by-step explanation:

volume=length×breadth×height

=9×5×9

405

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
