 (L · W · 2) + (perimeter of the base · height). For this prism, that's (2 cm · 3 cm · 2) + (2 cm + 2 cm + 3 cm + 3 cm) · 6 cm. This is (12 cm2) + (10 cm · 6 cm) = <span>72 cm2.</span>

Answer: =72\ cm^2,

Step-by-step explanation:

The total surface area of a right rectangular prism is given by :-

\text{Total surface area}=2(lw+wh+hl), where h is height, w is width and l is length of the prism.

Given: Height = 6 cm

Dimensions of base =  2 cm by 3 cm

Now, the total surface area of a given right rectangular prism is given by :-

\text{Total surface area}=2(2\cdot+3\cdot6+2\cdot6)=2(6+18+12)=2(36)=72\ cm^2,

Answer:

24 ft cubed

Step-by-step explanation:

The volume of a rectangular prism is denoted by the formula: V=lwh , where l is the length, w is the width, and h is the height.

Looking at the diagram, we can see that the length is 2 ft (so l = 2), the width is 4 ft (so w = 4), and the height is 3 ft (so h = 3). Now, we can just plug in these values to find V, the volume:

V=lwh

V=2*4*3=24

Thus, the answer is 24 ft cubed.

Hope this helps!
