Find the surface area of each figure. Round answers to the nearest hundredth.​

Answer 1

16) 560 cm²

17) 132 m²

Explanation:

To find the surface area of a right rectangular prism, we can use the following formula:

`\boxed{\begin{minipage}{7cm}\underline{Surface area of a right rectangular prism}\\\\$S.A.=2(wl+hl+hw)$\\\\where:\\\phantom{ww}$\bullet$ $w$ is the width of the base.\\ \phantom{ww}$\bullet$ $l$ is the length of the base.\\ \phantom{ww}$\bullet$ $h$ is the height of the prism.\\\end{minipage}}`

Question 16

From inspection of the given diagram, the dimensions of the right rectangular prism are:

• w = 10 cm
• l = 10 cm
• h = 9 cm

To calculate the surface area, substitute these values into the formula:

`\begin{aligned}\textsf{Surface Area}&=2(10 \cdot 10+9\cdot 10+9\cdot 10)\\&=2(100+90+90)\\&=2(280)\\&=560\; \sf cm^2\end{aligned}`

Therefore, the surface area of the right rectangular prism is 560 cm².

Question 17

From inspection of the given diagram, the dimensions of the right rectangular prism are:

• w = 2 m
• l = 8 m
• h = 5 m

To calculate the surface area, substitute these values into the formula:

`\begin{aligned}\textsf{Surface Area}&=2(2\cdot 8+5\cdot 8+5\cdot 2)\\&=2(16+40+10)\\&=2(66)\\&=132\; \sf m^2\end{aligned}`

Therefore, the surface area of the right rectangular prism is 132 m².

Answer 2

16. 560 cm²

17. 132 cm²

Explanation:

Solution Given:

The total surface area of a cuboid is calculated by adding up the areas of all six faces.

The formula is:

Total Surface Area of Cuboid = 2*(lw + lh + hw)

Where:

• l = length
• w = width
• h = height

For question no. 16.

• l=10 m
• w=10 m
• h=9 m

Substituting value in above formula:

Total Surface Area of Cuboid = 2*(10*10+10*9+9*10)

Total Surface Area of Cuboid= 560 cm²

For question no. 16.

• l=8 cm
• w=2 cm
• h=5 cm

Substituting value in above formula:

Total Surface Area of Cuboid = 2*(8*2+8*5+5*2)

Total Surface Area of Cuboid= 132 m²
