Rectangular prism A has a surface area of 25 square units and rectangular prism B has a surface area of 100 square units. Which statement accurately compares the dimensions of prism A to those of prism B ?(1 point) Responses Since prism B ’s surface area is 4 times as large as prism A ’s surface area, prism B ’s dimensions are 16 times as large as prism A ’s. Since prism upper B ’s surface area is 4 times as large as prism upper A ’s surface area, prism upper B ’s dimensions are 16 times as large as prism upper A ’s. Since prism B ’s surface area is 4 times as large as prism A ’s surface area, prism B ’s dimensions are half as large as prism A ’s. Since prism upper B ’s surface area is 4 times as large as prism upper A ’s surface area, prism upper B ’s dimensions are half as large as prism upper A ’s. Since prism B ’s surface area is 4 times as large as prism A ’s surface area, prism B ’s dimensions are twice as large as prism A ’s. Since prism upper B ’s surface area is 4 times as large as prism upper A ’s surface area, prism upper B ’s dimensions are twice as large as prism upper A ’s. Since prism B ’s surface area is 4 times as large as prism A ’s surface area, prism B ’s dimensions are 8 times as large as prism A ’s.

To analyze the relationship between the surface areas and dimensions of the prisms, we need to consider how surface area relates to the dimensions of a rectangular prism.

The surface area \( S \) of a rectangular prism with dimensions \( l \), \( w \), and \( h \) is given by the formula:

\[ S = 2(lw + lh + wh) \]

Now, prism A has a surface area of 25 square units, and prism B has a surface area of 100 square units. We can see that:

\[ \frac{S_B}{S_A} = \frac{100}{25} = 4 \]

This means that the surface area of prism B is 4 times that of prism A.

When comparing the dimensions of two similar geometric shapes, the ratio of their dimensions is the square root of the ratio of their surface areas:

\[ \text{ratio of dimensions} = \sqrt{\frac{S_B}{S_A}} = \sqrt{4} = 2 \]

This indicates that the dimensions of prism B are 2 times the dimensions of prism A.

Therefore, the accurate statement is:

"Since prism B’s surface area is 4 times as large as prism A’s surface area, prism B’s dimensions are twice as large as prism A’s."
