Question

Find the volume and surface area

Answer 1

Hey there! :)

First, let's find the volume

Volume = length × width × height

30 × 6 × 7 = 1260

The volume is 1,260 in³
______________________________________________________________

Surface Area: 

Small squares: 84
(7 × 6) · 2

Smaller rectangles: 360
(30 × 6) · 2

Bigger rectangles: 420
(30 × 7) · 2

Now, let's add all

84 + 360 + 420 = 864

The surface area is 864 in

Hope this helps :)
