#106392# meters squared.

Explanation:

Surface area of a rectangular prism or cuboid is given by:

#SA=2(lw+wh+lh)#

where:

  • #l# is the length of the cuboid

  • #w# is the width of the cuboid

  • #h# is the height of the cuboid

Here we have #h=398 \ "m",l=w=62 \ "m"# because there is a square base.

So we get:

#SA=2(398*62+62^2+398*62)#

#=2(24676+3844+24676)#

#=2*53196#

#=106392 \ "m"^2#
