Question

What would be the correct answer? 720cm2, 120cm2

Or 840cm2, 184cm2? Thank you for helping!! :D

Answer 1

length l = 10 cm

width w = 2 cm

height h = 6 cm

diagonal d = 11.832159566199 cm

surface area S = 184 cm²

volume V = 120 cm³

Explanation:

Surface Area of Rectangular Prism:

S = 2(lw + lh + wh)

Answer 2

184cm²

Explanation:

Surface area = 2(lb+bh+hl)

where , l ,b and h are the length , breadth and height of the cuboid respectively.

Here, l= 10cm , b= 2 cm and h= 6 cm

Surface area = 2(lb+bh+hl)

= 2[( 10×2)+(2×6)+(6×10)]cm²

= 2(20+12+60)cm²

= 2×92 cm ²

= 184cm²
