    use the formula LSA = 2*(L*H + W*H) where LSA = lateral surface area L = length W = width H = height

    in this case LSA = unknown (we're solving for this) L = 8 W = 6 H = 10

    so 2*(L*H + W*H), 2*(8*10+6*10), 2*(80+60) 2*140, 280 ?

    yep LSA = 2*(L*H + W*H) LSA = 2*(6*10 + 8*10) LSA = 2*(60 + 80) LSA = 2*(140) LSA = 280
