A cell phone box in the shape of a rectangular prism is shown. The height of the box is 4 cm.

The height of the original box will be increased by 3.5 centimeters so a new instruction manual and an extra battery can be included.

Which is closest to the total surface area of the new box?
A) 707 square centimeters

B) 479 square centimeters

C) 959 square centimeters

D) 738 square centimeters

it’s 959cm squared.

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°
