Answer :
The surface area of the shape is 256yd²
The surface area of the shape can be calculated by the following method.
The name of the shape is a cuboid
Surface area of a cuboid = 2lw + 2wh + 2hl
where l = length, w = width , h = height
From the diagram, l = 14yd, w = 2yd, h = 6.25yd
Substituting in the formula
= 2(14*2) + 2(2*6.625) + 2(6.25*14)
= 2(28) + 2(12.5) + 2(87.5)
expanding and multiplying the brackets gives
= 56 + 25 + 175
Surface area = 256
