The surface area of the box is 78in²

To determine the surface area, we have that the formula is expressed as;

S.A = 2(wl + hw + hl)

Such that the parameters of the formula are;

  • S.A is the surface area
  • l is the length
  • w is the width
  • h is the height

Now, substitute the values, we have;

Surface area = 2 ( 3×3 + 3 ×5 + 5×3)

multiply the values, we get;

Surface area = 2(9 + 15 + 15)

add the values

Surface area = 2(39)

multiply the value

Surface area = 78in²
