7.54 x 105 in standard notation = 754,000
3 x 5 x 7 = 105 cubic inches
5.8 x 8.3 inches or 148 x 210 mm
First convert ft and inches to inches by multiplying the feet by 12 and adding the inches. Then convert the inches to meters by multiplying by 0.0254 since 1 in = 0.0254 m (exactly): meters = (feet x 12 + inches) x 0.0254
Feet x 12 = inches
7.54 x 105 in standard notation = 754,000
The best way to do this is convert it all to inches. 148 inches by 143 inches. This gives you 21,164 square inches. Divide by 144 to get a total of 147 square feet.
Let the length be (x+8) and the width be x: length*width = area (x+8)*x = 105 sq inches x2+8x = 105 x2+8x-105 = 0 Solving the above quadratic equation works out as : x = -15 or x = 7 it must be the latter because dimensions can't be negative. Therefore: width = 7 inches and length = 15 inches Check: 7*15 = 105 sq inches
2.78 x 105
1.86 x 105
3 x 5 x 7 = 105 cubic inches
5.8 x 8.3 inches or 148 x 210 mm
Use this formula to convert inches to meters: inches x 0.0254 = metersSo, 3,600 x 0.0254 = 91.44 meters.
3.74274 x 105
If the exponents are the same, you can just subtract the coefficients. If not, you have to convert one to use the same exponent as the other first. For example, 3 x 105 - 2 x 105 = 1 x 105 But to subtract 5 x 105 from 4 x 106, you can convert the second number to 40 x 105. Then the answer is 35 x 105, or 3.5 x 106 Yes, I could have saved a step by converting the first number to 0.5 x 106 instead. Either way is correct.
Miles x 63,360 = inches
miles x 63,360 = inches: 32 x 63360 = 2,027,520 inches.
