Answer:
For a rectangular prism:
Surface Area = (2 × Area of Base) + (Perimeter of Base × Height)
Area of Base = L × W = 12 × 8 = ___ cm2
Perimeter of Base = 2L + 2W = 2·12 + 2·8 =___ cm2
Height = 4 cm
Explanation:
Surface area=(2× area of base)+(perimeter of base × height)
area of base=L × W= 12×8=____cm2
Perimeter of Base=2L+2W=2.12+2.8=_____cm2
height= 4 cm
