Surface Area= 2(lw + wh + lh)

= 2 (35 x 20 +20 x 30 + 35 x 30)

= 2 ( 700 + 600 +  1050)

= 2 x 2350

= 4, 700

The surface area of the outside of the fish tank is 4700 sq in.

Step-by-step explanation:

Given,

Length (l) = 35 in

Width (b) = 20 in

Height (h) = 30 in

To find the surface area of the outside of the fish tank.

Formula

The surface area of cuboid (A) = 2(lb+bh+lh)sq in

Now,

A = 2(35×20+20×30+30×35) sq in

= 4700 sq in

Hence,

The surface area of the outside of the fish tank = 4700 sq in.
