Question

Find the Volume and/or Surface Area. Use 3.14 for pi. Round answers to the nearest tenths, if necessary.​​​

Answer 1

To find the volume of this, we must find the area of the triangle and multiply it by the width of this prism.

Formula for area of triangle;

A = BH x 1/2

Replace values;

A = BH x 1/2

A = 3(4) x 1/2

A = 12 x 1/2

A = 12/2

A = 6, is the area of the triangle.

Now multiply it by the width:-

6(area of triangle) x 7(width)

= 42 cm3
