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.
