Step 1:

The length , width and height are l = 2 ; w = 2; h = 3

Step 2:

The surface area = 2(lw + wh + lh)

= 2(2×2 + 2×3 + 2×3)

= 2(4 + 6 + 6)

= 32 square units

Q 2 - Find the length, width and height of the following rectangular prism. Then find its surface area. ### Explanation

Step 1:

The length , width and height are l = 4 ; w = 3; h = 2

Step 2:

The surface area = 2(lw + wh + lh)

= 2(4×3 + 4×2 + 2×3)

= 2(12 + 8 + 6)

= 52 square units

Q 3 - Find the length, width and height of the following rectangular prism. Then find its surface area. ### Explanation

Step 1:

The length , width and height are l = 5 ; w = 5; h = 3

Step 2:

The surface area = 2(lw + wh + lh)

= 2(5×5 + 5×3 + 5×3)

= 2(25 + 15 + 15)

= 110 square units

Q 4 - Find the length, width and height of the following rectangular prism. Then find its surface area. ### Explanation

Step 1:

The length , width and height are l = 3 ; w = 5; h = 5

Step 2:

The surface area = 2(lw + wh + lh)

= 2(3×5 + 3×5 + 5×5)

= 2(15 + 15 + 25)

= 110 square units

Q 5 - Find the length, width and height of the following rectangular prism. Then find its surface area. ### Explanation

Step 1:

The length , width and height are l = 3 ; w = 3; h = 2

Step 2:

The surface area = 2(lw + wh + lh)

= 2(3×3 + 3×2 + 2×3)

= 2(9 + 6 + 6)

= 42 square units

Q 6 - Find the length, width and height of the following rectangular prism. Then find its surface area. ### Explanation

Step 1:

The length , width and height are l = 4 ; w = 2; h = 5

Step 2:

The surface area = 2(lw + wh + lh)

= 2(4×2 + 4×5 + 2×5)

= 2(8 + 20 + 10)

= 76 square units

Q 7 - Find the length, width and height of the following rectangular prism. Then find its surface area. ### Explanation

Step 1:

The length , width and height are l = 2 ; w = 5; h = 5

Step 2:

The surface area = 2(lw + wh + lh)

= 2(2×5 + 2×5 + 5×5)

= 2(10 + 10 + 25)

= 90 square units

Q 8 - Find the length, width and height of the following rectangular prism. Then find its surface area. ### Explanation

Step 1:

The length , width and height are l = 2 ; w = 3; h = 4

Step 2:

The surface area = 2(lw + wh + lh)

= 2(2×3 + 2×4 + 4×3)

= 2(6 + 8 + 12)

= 52 square units

Q 9 - Find the length, width and height of the following rectangular prism. Then find its surface area. ### Explanation

Step 1:

The length , width and height are l = 5 ; w = 3; h = 2

Step 2:

The surface area = 2(lw + wh + lh)

= 2(5×3 + 5×2 + 2×3)

= 2(15 + 10 + 6)

= 62 square units

Q 10 - Find the length, width and height of the following rectangular prism. Then find its surface area. ### Explanation

Step 1:

The length , width and height are l = 3 ; w = 5; h = 4

Step 2:

The surface area = 2(lw + wh + lh)

= 2(3×5 + 4×3 + 5×4)

= 2(15 + 12 + 20)

= 94 square units
