One face of the cube has area =2²=4m²
Cube has 6 equal faces, so surface area of the cube=6*4m²= 24 m²
2.5*7 = 17.5. If it's easier for you, multiply 2.5 by 5 then add 2.5*2.
A rational number is any number that can represented as a fraction of two integers (when the denominator isn't 0). As decimals, rational numbers can be either terminating or repeating.
All integers are rational numbers because they can be expressed as x/1.
An example of a rational number that isn't an integer is 2/3.
Answer:
Forest area burned by the fire is 256000 acres.
Step-by-step explanation:
Use the unitary method to calculate the area of National park burned in acres.
Since, 1 square mile = 640 Acres
Therefore, 400 square miles = 640 × 400
= 256000 acres
Hence, forest area burned by the fire is 256000 acres.
