Answer:

Total surface area of a cuboid is 376 square centimeter.

Step-by-step explanation:

Given : A cuboid of length 10 cm breadth 8 cm and height 6 cm.

To find : The total surface area of a cuboid?

Solution :

The total surface area of a cuboid is

Where, l is the length l=10 cm

b is the breadth b=8 cm

h is the height h=6 cm

Substitute the value in the formula,

Therefore, Total surface area of a cuboid is 376 square centimeter.

Answer:

344 sq.cm

Step-by-step explanation:

total surface area of cuboid = 2 (lb + bh + lh)

( where l = length, b = base, h = height )

T.S.A = 2 (10×6) + (6×7) + (10×7)

=》2 (60 + 42 + 70)

=》2 × 172

=》344

zhannawk [14.2K]

Answer:

Space between 80 evenly spaced chairs = 21m

Step-by-step explanation:

So, according to the given statement, we have the following expression:

No. of chairs ∝ $\frac{1}{Distance.Between.chairs}$

70 chairs are 24m apart, so it can be written as:

70 ∝ $\frac{1}{24}$

For, 1 chair , we divide both sides by 70

$\frac{70}{70}$ ∝ $\frac{1}{24(70)}$

1 ∝ $\frac{1}{24 (70)}$ -----------------------(Equation 1)

For 80 chairs:

Multiply both sides of Equation.1 by 80

80 ∝ $\frac{80}{24 (70)}$

80 ∝ $\frac{1}{21}$

So according to the above relation,

80 evenly spaced chairs will have a space of 21 m between them.

In the figure, b and c are parallel lines. Which of the following statements are true?

Helen [10]

Answer:

1. No, Joe is not correct

2. $\angle 5=72^{\circ}$

Step-by-step explanation:

Given: b and c are parallel lines

To find:

1. whether the given statement is correct or not

2. $\angle 5$

Solution:

Sum of two angles that form a linear pair is equal to $180^{\circ}$

$\angle 3+72^{\circ}=180^{\circ}$ (linear pair)

$\angle 3=180^{\circ}-72^{\circ}=108^{\circ}\neq 90^{\circ}$

So, Joe is not correct

If two lines are parallel then alternate interior angles are equal.

As b and c are parallel lines,

$\angle 5=72^{\circ}$ (alternate interior angles)
