<u>Given</u>:
Given that the side length of the cube is 1.8 cm
We need to determine the lateral surface area of the cube.
<u>Lateral surface area of the cube:</u>
The lateral surface area of the cube can be determined using the formula,
where a is the side length.
Substituting a = 1.8 in the above formula, we get;
Squaring the term, we get;
Multiplying, we get;
Thus, the lateral surface area of the cube is 12.96 cm²
Answer:
We conclude that total cost/bill will be: $27.81
Step-by-step explanation:
Given
The cost of an iPhone case = $27
Additional expense = 3% = 3/100 = 0.03
To determine
Total bill = ?
The expense amount can be calculated by multiplying the cost of an iPhone case by the additional expense
i.e.
Expense Amount = cost of an iPhone case × additional expense
= 27 × 0.03
= $0.81
The total cost is calculated by adding the expense amount and the original cost of an iPhone case.
i.e.
Total cost/bill = Expense Amount + cost of an iPhone case
= $0.81 + $27
= $27.81
Therefore, we conclude that total cost/bill will be: $27.81
Answer:
Step-by-step explanation:
105 (11/12)
Answer: 25
Step-by-step explanation:
Finding the product of complex numbers is not different to finding the product of real numbers
(-3i+4) * (3i+4) = -9i^2 + 12i - 12i + 16 = 25
