Answer:
Surface area of rectangular prism = 250 cm²
Step-by-step explanation:
The rectangular prism is Prism B
Surface area of rectangular prism = 2lw + 2hw + 2lh
Where,
h = 10 cm
w = 5 cm
l = 5 cm
Plug in the values
Surface area of the rectangular prism = 2(5)(5) + 2(10)(5) + 2(5)(10)
= 50 + 100 + 100
= 250 cm²
