2√72 / √8 ± √2
If the denominator is √8 + √2,
2√72 / √8 + √2
= 2√(2*2*2*3*3) / √(2*2*2) + √2
= 2*2*3√2 / 2√2 + √2
= 12√2 / 3√2
= 4
Answer:
V = 6 or V = -6
Step-by-step explanation:
Solve for V over the real numbers:
V^2 = 12^2 - 6 2 9
12^2 + 2 (-6) 9 = 36:
V^2 = 36
Take the square root of both sides:
Answer: V = 6 or V = -6
Answer:
The answer to your question is: 3600 cm ²
Step-by-step explanation:
Rectangular box:
length = 40 cm
breadth = 25
height = 20 cm
Area =
Area of the base = 40 x 25 = 1000 cm²
Area of the lateral sides = 2(40 x 20) = 1600 cm²
Area of the sides = 2(25 x 20) = 1000 cm²
Total area = 1000 + 1600 + 1000 = 3600 cm²
