Question

Ray had a block of wood in the shape of a rectangular prism. The block and it's dimensions are shown below:

Answer 1

Answer:

$(a)\ Area = 24in^2$

$(b)\ Area = 60in^2$

Step-by-step explanation:

Given

See attachment for the dimension of the block

Solving (a): Area of the front face

From the attachment, the front face has the following dimension.

$Length = 4in$

$Width = 6in$

The area is calculated as:

$Area = Length *Width$

$Area = 4in * 6in$

$Area = 24in^2$

Solving (b): Area of the top and bottom faces

The top and bottom faces have the same dimension

From the attachment, the top face has the following dimension.

$Length = 5in$

$Width = 6in$

The area of the top is calculated as:

$Area = Length *Width$

$A_1 = 5in * 6in$

$A_1 = 30in^2$

The area of the top and the bottom faces is:

$Area = 2 *A_1$ ---- because the top and bottom faces have the same dimension

$Area = 2 *30in^2$

$Area = 60in^2$
