Adelivery truck company just bought a new delivery

A) 760 ft³

Step-by-step explanation:

The surface area of the figure has to be calculated.

Step 1: Divide the figure

The figure is divided into the following parts to calculate the volume.

Part 1: Box without ledge

Formula for volume of rectangle = length x width x height

Volume = 14.3 x 7.8 x 6.6

Volume = 736.164 ft³

Part 2: Box with ledge-we will only calculate height and width since the length has already been included in part 1 therefore including it again would result in double counting and give the wrong answer.

Volume = height x width

Volume = 2.7 x 7.8

Volume = 21.06 ft³

Step 2: Add both volumes to find the total volume

Volume part 1 + Volume part 2 = 736.164 ft³ + 21.06 ft³

= 757.224 ft³ rounded off to nearest tenth = 760 ft³

Therefore, answer A is correct.

!!

A)A reflection can be used to create DBE

B)The Angles are congruent, as the transformation was rigid, which preserves angle measure and side length.

C)All the angles are corresponding to the second figure as well as the sides. (name all the sides and angles that are corresponding)

Ex: ABC=DBE

Hope this helps!

P.S. Stay Safe!
