Question

Find The Surface Area

Answer 1

A = (12 x 8 x 3) + (1/2 x 8 x 6.9) + (1/2 x 8 x 7 x 3)

A = 288 + 27.6 + 84

A = 399.6 m²

Answer 2

Answer:

A = (12 x 8 x 3) + (1/2 x 8 x 6.9) + (1/2 x 8 x 7 x 3)

A = 288 + 27.6 + 84

A = 399.6 m²

Step-by-step explanation:

The area =12(8x3)+(1/2)(8x6.9)+(1/2)(7x3)

The area = (288)+(27.6)+(84)

The area = 399.6 m ²
