Answer:
Total surface area of cube = 294 cm²
Step-by-step explanation:
Given:
Perimeter of cube = 84 cm
Find:
Total surface area of cube
Computation:
Perimeter of cube = 12 x side
84 = 12 x side
Side = 7 cm
Total surface area of cube = 6(a)²
Total surface area of cube = 6(7)²
Total surface area of cube = 294 cm²
Answer:
18
Step-by-step explanation:
=2(cot²A+1)
=2cosec²A. [` . ` cot²A+1=cosec²A] =2(1/sinA)²
[' . 'cosecA=1/sinA]
=2×3²/1
=2cot²a+2=2×8+2=16+2=18
Answer:
Bruno = 15 years
Mother = 8 + 2(15) = 38 years
Father = 38 + 3 = 41 years
Step-by-step explanation:
Given that :
Let
Bruno's age = x
Mothers age = 8 + 2x
Father's age = 8 + 2x + 3 = 2x + 11
x + 8 + 2x + 2x + 11 = 94
5x + 19 = 94
5x = 75
x = 75 /5
x = 15
Bruno = 15 years
Mother = 8 + 2(15) = 38 years
Father = 38 + 3 = 41 years
