Answer:
surface area = 28 yard²
Step-by-step explanation:
given data
1 unit length of cube = 1 yd
solution
As given image shown that rectangular solid has length 5 units, width 2 units, and height 2 units.
so we get here surface area that is we get by area of each of its faces
we can see three face are
A front = L × W = 2 × 2 = 4
A side = L × W = 5 × 2 = 10
A top = L × W = 5 × 2 = 10
so here
surface area = ( front + back ) + ( left side + right side ) + ( top + bottom ) ................1
surface area = ( 2 × front ) + ( 2 × left side ) + ( 2 × top )
surface area = ( 2 × 4 ) + ( 2 × 10 ) + ( 2 × 10 )
surface area = 8 + 20 + 20
surface area = 28 yard²
