Find the surface area

Mathematics
1 answer:
raketka [301]3 years ago
8 0

Answer:

Total surface area = 217 cm²

Step-by-step explanation:

Area of Triangle = 1/2*b*h

Area of Triangle = 1/2 * 7 * 12 = 42 cm²

There are four triangular surfaces in the prism = 4 * 42 = 168 cm²

Area of the base square = S² = 7 x 7 = 49 cm²

Total surface area = Area of the base square + Area of 4 triangular surfaces

Total surface area = 49 cm² + 168 cm²

Total surface area = 217 cm²

xenn [34]

Answer:

10 grams or 0.010kg

Step-by-step explanation:

The mass of the bag used to make flour is 2.26 kg = 2260 grams

Now, in order to find out how many badges she made, we would need to divide the weight of the bag by the amount needed to make a badge.

Therefore: \frac{2260}{450}  = 5.02

We know now that the bag will make 5 batches and will have some left over. In order to find how much we used, we can multiply 5 * 450 = 2250.

Therefore, in order to make 5 batches, Maria used exactly 2250 grams of flour which in result left us with 10 grams of the bag.

Note: 2260 -2250 = 10 grams.

Subtract, in order to find how many you have left.

Hope this helps.

Dafna11 [192]

Answer:

5000 particles of size 10 nanometer should be stacked

Step-by-step explanation:

Average diameter of the of the human hair = 50 micron = 50 × 10⁻⁶ m

Now,

let the number of 10 nanometer i.e 10 × 10⁻⁹ m particle be 'n'

thus,

n × 10 × 10⁻⁹ m = 50 × 10⁻⁶ m

Therefore to find the number of 10 nanometer i.e 10 × 10⁻⁹ m particle,

n = \frac{50\times10^{-6}}{10\times10^{-9}}

or

n = 5000

Hence,

5000 particles of size 10 nanometer should be stacked
