Answer:
v=9 cm³
sa=30 cm²
Step-by-step explanation:
v=3*3*1=9cm³
sa=(2*3*3)+(4*3*1)=18+12=30 cm²
Volume of rectangular prism is 9 [tex]cm^{3}[/tex], Surface area of rectangular prism is 30 [tex]cm^{2}[/tex].
To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.
Volume = L × W × H
To find the surface area of a rectangular prism, measure the length, width, and height of the prism. Find the area of the top and bottom faces by multiplying the length and width of the prism. Then, calculate the area of the left and right faces by multiplying the width and height.
Surface area = 2(LW + WH + LH)
Given
L = 3cm
W = 1cm
H = 3cm
Volume of rectangular prism = L × W × H
= [tex]3 \times 1 \times 3[/tex]
= 9 [tex]cm^{3}[/tex]
Surface area of rectangular prism = 2(LW + WH + LH)
= [tex]2(3 \times 1 + 1 \times 3 + 3 \times 3)[/tex]
= [tex]2(3+3+9)[/tex]
= [tex]2(15)[/tex]
= 30 [tex]cm^{2}[/tex]
Volume of rectangular prism is 9 [tex]cm^{3}[/tex], Surface area of rectangular prism is 30 [tex]cm^{2}[/tex].
