Find the lateral and total surface area of the prism.
tia_tia [17]

Lateral surface area of the prism = 920 in²

Total surface area of the prism  = 1180 in²

Solution:

Length of the prism = 13 in

Width of the prism = 10 in

Height of the prism = 20 in

Lateral surface area of the prism = 2(l + w)h

                                                       = 2(13 + 10) × 20

                                                       = 2(23) × 20

                                                       = 920 in²

Lateral surface area of the prism = 920 in²

Total surface area of the prism  = Lateral area + 2lw

                                                     = 920 + 2 × 13 × 10

                                                     = 920 + 260

Total surface area of the prism  = 1180 in²

Hence Lateral surface area of the prism = 920 in²

Total surface area of the prism  = 1180 in²

the area of a rectangular photograph is 35 square inches. If the width of the photo is 5 inches how tall is the photo
Vika [28.1K]
We know that:

Area= length*width

Plug in the stuff you know.

35= length(tall)*5

Divide both sides by 5.

7= length

The photo is 7 inches tall.

I hope this helps!
