Answer

A) 2160 cubic inches

Step by step explanation

Volume of a rectangular prism = length *width*height.

The give figure (stairway) consists of two rectangular prism.

The volume of the first rectangular prism (bigger one) = 12 *10*12

=120*12

1 st prism = 1440 cubic inches

The volume of the rectangular prism 2 (smaller one) = 12*10*6

=120*6

The volume of the rectangular prism 2 = 720 cubic inches

The volume of the concrete stairway = Volume of the prism 1 + Volume of the prism 2

= 1440 + 720

The volume of the concrete stairway = 2160 cubic inches.

Thank you.

Am i doing this right????
Anna35 [415]
You are going in the right direction. For the distance of ST I get √136
√(-5-1)² + (6+4)² =
√(-6)² + (10²) =
√ 36 + 100 =
√136

√34² + √136² =√170²
34 + 136 = 170
170 = 170
