Surface Area (S.A.) is the sum of the area of the base and all of the faces

Area of the base = 6 x 6 = 36
Area of one of the faces = (1/2) b x h = (1/2) x 6 x 9 = 27

There are 4 faces so the sum of the areas = 36 + 4(27) = 144 ft²

Prove by factorization √16×81=√16×√81
Oksanka [162]

Answer:

√16×81 = 4×9 or √1296 = 36

√16×√81 = 4×9 = 36

Step-by-step explanation:

√81×16

We simplify 81 and 16 by prime factorisation (expressing a number as a product of its prime factors).

√81 = √3×3×3×3 = √9×9 = √9² = 9

√16 = √2×2×2×2 = √4×4 = √4² = 4
