Answer:

The answer would be 31.5

Explanation:

First it's a rectangular

Second we would convert the fraction to decimal so 1 1/2 would be 1.5 and 2 1/2 would be 2.5

so the formula of the rectangular 2(wl + hl + hw)

so 2(1.5 × 2.5 + 3 × 2.5 + 3 + 1.5)

it would be 31.5 if we do the math

hope it helped.

Answer:

31.5

Explanation:

You need to first use the formula of calculating surface area of a cuboid

SA=2(lw+lh+wh)

now you put the values in as

H=3

W=1.5

L=2.5

You get 31.5

Hope this Helps!
