The inner dimensions of a cuboidal wooden box are 30cm x 20cm x 10cm and its outer dimensions are 32cm x 22cm x 12cm. Find the mass of the box if 1 cm3
of wood has a mass of 0.6g

332.2g

Step-by-step explanation:

30 x 30 x 10 = 9000

32 x 22 x 12 = 8448

9000 - 8448 = 552

552 x .6 = 332.2g

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
