B I hope

Step-by-step explanation:

The length of the base of a square prism is 3.872 cm and the surface area of a square prism is 184.9 cm ²

Volume of a square prism

Let h is the height length of the prism and a is the length of base edge.

then the volume is a²h and the surface area is 2a²+4ah

How to base length?

(a) The volume of a square prism is 150 cm³ and  10 cm is height length

Let a is the length of base edge.

We know the volume is a²h.

Substitute the values

a²(10) = 150

     a² = 15

      a = √15

      a = 3.872 cm

Since length of base is 3.872 cm.

How to find the surface area of a square prism?

(b) The height length of the prism is 10 cm and the base edge length is √15 cm.

We know the surface area is 2a²+4ah

Substitute the values

S = 2(√15)² + 4 (3.87 )(10)

  =  2(15) + 40(3.87)

  = 30 + 154.91

  = 184.9 cm ²

Since the surface area of a square prism is  184.9 cm ².
