Full question on picture

Each edge of the box is 3 ft, and to get the volume we need to do L * W * H. Because all three are 3, it's just 3 * 3 * 3, which is 27 ft³ for the volume of the box.

Now, what's the volume of 10 of these boxes? To get that, we just multiply the volume of the original box by 10. 27 * 10 makes 270 ft³.

11

step-by-step explanation:

32.50-7.50=25

225/25=11

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
